Preface 

This Portfolio of Dcrmochromes contains two hundred and sixty- 
six colored and six black and white illustrations. All of the colored 
plates are from Jacobi's "Atlas der Hautkrankheiten " and two hun- 
dred and seventeen of the figures appeared in the fourth American 
edition of this work, known here as the Jacobi Dermochromes. Tho re- 
maining forty-nine figures are from the fifth Geniian edition of tho 
Atlas and are now, by arrangement with the German publisher, pre- 
sented for the first time in this country. The black and white illustra- 
tions, representing different types of alopecia, are from photographs 
taken for me by Dr. William B. Trimble. 

Although many of the plates will be familiar to Amorioan phy- 
sicians, the accompanying text is entirely new. In its preparation the 
writings of the leading American, British, and Continental denna- 
tologists have been freely consulted, but preference has generally been 
given to the views of the fonner, as the work is intended chiefly for 
readers in tliis country. I particularly desire to acknowledge manifold 
obligations to Drs. Bulkley, Duhring, Pusey, and Stclwagon. 

The section on syi^hilis was intrusted to Dr. William Gaynor States, 
and I greatly appreciate the honor of having his able presentation of 
this disease incorporated in this work. 

To my clinical associates at the New York Skin and Cancer Hos- 
pital I am indebted for considerable assistance ; to Dr. Paul E. Beehet 
and Dr. Arthur M. Kane for valuable aid in preparing the manuscript 
and in passing the work through the press, and to Dr. Biuford Throne 
for the excellent chapters on the exanthemata. I here take pleasure in 
expressing to them my tlianks for their generous cooperation. 

The subjects have been grouped, as far as practical, according to 
generally accei)ted pathological classifications, jind with but few excep- 

r 



tlons the nomenclature recommended by the American Dermatological 
Association has been adhered to in the text. 

"While fully realizing that in a work of this scope individualism is 
out of place, I must confess that I have not always refrained from the 
temptation to interject personal impressions and opinions. 

JEROME KINGSBURY.

Erythema Multiforme 

Plate 1, Figs. 1 and 2 

Erythema multiforme is an acute dermatosis having certain affin- 
ities with urticaria and purpura and hence believed to be essentially 
angioneurotic in character and dependent on some irritant within the 
blood which is chiefly of intestinal origin. It differs from an ordinary 
toxic rash in the large amount of infiltration, and in its appearance in 
successive crops. "While eminently multiforme, in the majority of 
cases, the lesions are more or less uniform in that there is a predom- 
inant type. The affection differs from those which most resemble it in 
a tendency to appear in certain localities, as the upper extremities 
below the elbows, the legs and feet and the face. It prefers the 
exterior surfaces, as a rule. In certain cases the entire surface of 
the body may be involved, and even some of the adjacent mucous 
membranes. Unlike most acute eruptions, it gives rise to little sub- 
jective discomfort. 

A constitutional reaction from the eruption or in association with 
it seldom occurs, but erythema multiforme may represent a manifesta- 
tion of some general infection which is akin to acute rheumatism. In 
occasional cases there is serious organic disease of the abdominal 
organs. These modes of behavior make it appear probable that the 
affection is a syndrome and not an actual disease. 

The conunonest form is a papular efflorescence, the lesions of 
which do not exceed the size of a large pea. The papules may be dis- 
crete or aggregated. Less common are tubercles which are consider- 
ably larger and accompany the smaller lesions. All these lesions tend 
to flatten and broaden and leave a depression, so that a ring may be 
formed. The color, a dark vinous red, is almost characteristic. Some- 
times rings of considerable size are formed, and segments of rings 
may be combined to form certain patterns; or one ring may form 
within another. In severe cases a papule or tubercle may have a 
vesicular centre. Aside from this there is a typical vesicular form 



known as erythema iris which will be described later. Bullous and 
purpuric forms bear a close resemblance to pemphigus and purpura 
and perhaps tend to partake of the nature of those affections. 

Etiology 

As already stated, the affection appears to be a syndrome which 
may be due to a great variety of causes — ^various circulating poisons, 
some of which may be the product of intestinal autointoxication. The 
affection may sometiines appear as an equivalent to an attack of 
dermatitis medicamentosa, and at times it is doubtless the result of a 
bacteriotoxemia. It is a disease of relatively early years and fre- 
quently attacks unacclimated subjects. Its most salient anatomical 
feature appears to be the cell proliferation which gives the peculiar 
fixed character to the lesions. 

Diagnosis 

The disease most closely resembles urticaria when the wheals of 
the latter are red. Urticarial lesions, however, are very fugacious, 
accompanied by much itching and burning, and seldom form rings. 
The latter when highly developed suggest ringworm, but this can 
hardly appear as a more or less extensive, symmetrical eruption. 
While erythema nodosum may coexist, there should be no confusion, 
for although the two affections have much in common, their lesions 
are quite dissimilar. 

Prognosis 

If the affection be regarded as a syndrome, the prognosis will de- 
pend on the actual cause of the disease. The eruption subsides com- 
pletely in two or three weeks, but some cases tend to recur at short 
intervals. 

Treatment 

The bowels should first be well evacuated, and after this intestinal 
antiseptics and antirheumatic medication administered. Capsules of 
salol gr. v., three or four a day, are useful, and frequent and mod- 
erately large doses of quinine are at times of service. If rheumatic 
symptoms are at all marked salicylate of soda should be given in full 
doses. There is but little local treatment required, as the lesions soon 
run their course and give rise to but little disturbance. In some 
cases, however, the itching and burning are quite troublesome, and for 



one that is generally found satisfactory : 

these cases antipruritic lotions may be prescribed. The following is

Erythema Iris 

Synonym: Herpes iris 
Plate 2, Figs. 3 and 4 

Whether this eruption is a simple clinical variety of erythema mul- 
tiforme or a distinct affection affiliated with it, was formerly a vexed 
question, but at present authorities seem to have decided upon the vir- 
tual identity of the two. There may, however, be as good reasons for 
the dualistic view in the case of erythema iris as in erythema 
nodosum. 

In erythema iris we see a particular type of erythema, attended in 
the great majority of cases with vesiculation ; so that the former may 
be regarded as an abortive phase. In other forms of erythema multi- 
forme vesiculation is exceptional. The process of vesiculation in 
erythema iris also resembles that of true herpes, for the vesicles ap- 
pear promptly and with the same stinging sensation. Moreover, it is 
sometimes seen in association with herpes facialis and herpes pro- 
genitalis. 

Erythema iris consists of concentric rings of erythema, which, 
like other lesions, run their course rapidly, and since the rings appear 
in succession, exhibit different shades of color suggestive of the 
deeper hues of the rainbow — bright red, purple and violet, the older 
rings being of the latter shades. In this process the new rings form 
outside of the old ones, developing from a red areola ; and the nmnber 
may vary from two to six. As already stated, the process of vesicula- 
tion begins early, within twelve hours, so that lesions of different 
degrees of development appear side by side. From the formation of 
concentric rings, large patches are formed and may coalesce. 

The vesicles are essentially small but coalesce in the rings, and ex- 
ceptionally the central vesicle may form a bulla of variable size with 
which the outside vesicles may coalesce. The vesicles last about a 
week and disappear by absorption. 

The distribution of erythema iris agrees mth that of erythema

multiforme in every respect in both typical and exceptional cases, and 
the treatment presents no peculiarities, save that large bullae may 
require evacuation.

Erythema Nodosum 

Synonyms: Dermatitis contusifonnis. (Fr.) Erytheme nouveux 

Plate 3, Fig. 5 

This affection is in many respects very closely related to erythema 
multiforme. It possesses, however, features particularly its own, 
thus affording a convenient excuse to describe it as a separate 
disease. 

In most text-books it is referred to as an affection of childhood 
and adolescence, but adults are by no means immune, and I can re- 
call, from my own practice, a typical case that occurred in a woman 
sixty years of age. For some unknown reason the disease is very 
much more common in females than in males. The characteristic le- 
sions of erythema nodosum consist of more or less elevated node-like 
swellings. These occur most commonly over the shins, and as a rule 
both legs are affected. The nodes have no well-defined border, and in 
size they vary from that of a hazel-nut to a mass sometimes as large 
as a hen's egg. They are generally oval in shape, and their long axis 
corresponds to that of the limb. The color is at first bright red, but 
soon blue, and then purplish tints appear, and as absorption pro- 
gresses, it gradually fades to a yellowish hue, and at this time the 
lesions resemble bruises ; this explains one of the titles that has been 
given to this affection by some authors (dermatitis contusiformis). 
The swellings when they first appear are hard and tense, but they be- 
come softer as the inflammation subsides. At times a sensation of 
fluctuation is obtained, but the lesions never suppurate. Nodes not in- 
frequently occur on the flexor surface of the legs and occasionally on 
the thighs, buttocks, and forearms. The individual nodes last about 
two weeks, but new lesions sometimes continue to appear, even in 
cases that are under treatment, and the duration of an attack ranges 
from three to six weeks. When the nodes first appear, they are gen- 
erally preceded and accompanied by a greater or less degree of con- 
stitutional disturbance. At times there are symptoms referable to 
derangements of the gastro-intestinal tract, but the most constant

Fig. 6. Purpura hemorrhagica. 



concomitant symptoms are tliose of acute articular rheumatism of the 
extremities, the lower being more frequently affected. 

Etiology 

Erythema nodosum is so frequently associated with dofinito rheu- 
matic symj)toms, that it is now very generally looked upon as an ex- 
pression of rheumatism. 

Diagnosis 

This is seldom difficult, but at times the resemblance of inflamed 
syphilitic gummata to the lesions of erythema nodosum is quite 
marked. In sj-philis, however, the development of the lesions is more 
indolent, their number less, and they are not likely to be accompanied 
by constitutional sj-mptoms. In complicated cases the Wassermann 
or the Noguchi reaction should be of considerable assistance. 

Occasionally cases of erythema induratum are confused with those 
of erythema nodosum, but the former affection is a more chronic one, 
the lesions are much smaller, are generally found on the calf of the 
leg, and even in comparatively recent cases there is generally either 
ulceration or evidence of beginning central necrosis. In erythema 
induratum a positive tuberculine reaction is invariably obtained. 

Prognosis 

This is favorable as far as the disappearance of the lesions is con- 
cerned, but their development should be looked upon not only as an 
evidence of rheumatism but of impaired vitality as well, and the pos- 
sibility of an already existing endocarditis should be ascertained. 

Treatment 

If the swellings are very painful and the rheumatic symptoms se- 
vere, it is advisable to have the patient remain in bed for a few days 
or a w^eek. Although desirable, this is seldom absolutely necessary. 
The diet, however, should be restrictive, especially so if the febrile 
sjTnptoms are at all marked. In adults the bowels should be well 
moved by calomel, followed by the usual saline, but with children a 
dose of castor oil may be substituted. Although some observers have 
questioned its rheumatic relationship, it is a clinical fact that in 
erythema nodosum better results are obtained with antirheumatic 
medication than with any other. 

In mild cases, three to eight grains of aspirin or salicin in capsules 
may be given three or four times a day, but in cases where the rheu- 



matic symptoms are well defined it is better to administer full doses 
of the salicylate of soda, preferably in a mixture. The following for- 
mula is most efficacious : 

IJ Potassii acetatis oiii 

Sodii salicylatis 3iv 

Tinct. nuc. vomicas oil 

Syr. zingiber ad §iii 

M. et ft. mist. 

Signa Si in water after meals. 

After the swellings have disappeared, tonic doses of quinine may 
be given. For the anaemia that is frequently present iron and arsenic 
is indicated. The following is a valuable mixture :

Liq. potasssB 3iss. 

Vini ferri dulcis ad ^iii 

M. et ft. mist. 

Signa 3i in water after meals. 

Local applications are seldom necessary, but in the acute stage if" 
the nodes are particularly painful relief may be obtained from com- 
presses of ice, cold water, or of lead and opium wash.

Purpura Hemorrhagica 

Plate 3, Fig. G; and Plate 4, Fig. 7 

This affection is an unsatisfactory one to discuss because purpura 
is a generic term for all hemorrhages of the skin, and thus in a sense 
all purpura is hemorrhagic. The term was originally applied to 
morbus maculosus WerDiolii or land scurvy, an affection long believed 
to be sui generis and to exhibit no lesions other than hemorrhages 
into the skin, mucosae and often in the viscera ; in other words, an idio- 
pathic acute or chronic hemorrhagic diathesis or acquired hemophilia. 
In recent times good authorities have insisted that the condition is 
only an intensive form of purpura simplex, while others appear to be- 
lieve that there is no form of purpura which may not develop into the 
affection in question, and the latter may appear as an equivalent of 
other clinical forms of purpura. 

In some cases a constitutional reaction of malaise, fever, rhemiia- 
toid pains, gastro-enteric disturbances, etc., precedes the hemor- 
rhages, but the more marked are these the more certain it seems that 
the disease in the special case is essentially one of the ordinary erup- 
tive forms of purpura. Prodromes do not seem essential to the de- 
velopment of the disease and the earliest sjTnptoms may be directly 
dependent upon the loss of blood. The eruption appears on the 
trunk and limbs and at times upon the face, which latter location is 
regarded by some as pathognomonic of purpura hemorrhagica, as is 
also the occurrence of hemorrhages in the visible mucosa?. A fact of 
importance in purpura hemorrhagica which may assist to some extent 
in differentiating it from minor forms is the semitraumatic character 
of the lesions. 

The eruption may comprise every tj^pe of hemorrhagic cutaneous 
lesions from petechias to ecchymomata. The typical lesion is probably 
a large, flat extravasation or ecchymosis. 

A patient with purpura hemorrhagica may present sj-mptoms as- 
sociated with the exciting causes Avhen these are markedly in evi- 
dence, and also others due to loss of blood, such as pallor and prostra- 
tion. The disease may run a brief and benign course, recovery ensu- 
ing within a fortnight, or a sort of status may be established in 
which hemorrhages recur and the condition may then be termed 



chronic or at least subacute. The very acufe, fatal cases in wliich 
death occurs from internal hemorrhages have sometimes begun as 
relatively mild purpura. 

Etiology 

The chief point of interest in this connection is the nature of the 
factors which cause this severe degree of purpura. The latter has 
often been noted in a relatively pure form in syphilis, tuberculosis, 
nephritis, influenza, etc., differing essentially from the hemorrhages 
which depend directly on the exanthemas of variola, scarlatina, etc. 
Of vital significance especially in cumulative incidence is the possi- 
bility of a dietetic factor — insufficient nutriment with especial refer- 
ence to potash. 

Cases of so-called "land scurvy" occurring in pseudo epidemics 
are still reported from time to time, and usually recover as soon as 
the diet is regulated. 

The pathology is of the simplest, yet quite obscure in essence. 
The blood-vessels and blood seem both at fault. The former permit 
diapedesis and also readily rupture. The blood which escapes shows 
delayed coagulation. The absorption of the extravasated blood 
occurs more slowly than in traumatic cases. 

Diagnosis 

The implication of the mucosae and face, as well as evidences of 
internal hemorrhage will serve to differentiate purpura hemorrhagica 
from the more common and comparatively benign forms of purpura. 

Treatment 

The general management consists essentially in the use of hemo- 
static remedies, as rest in bed with foot of same elevated, cold appli- 
cations and the internal administration of ergot and adrenalin. 
Roller bandages on ihe legs may prevent further extravasations. If 
several cases develop in a small community or house, the diet should 
be carefully considered as to the content of the food in potash. For 
the debility following an attack the patient should be put on a gener- 
ous diet of meat and fresh vegetables, with wine. Iron, quinine, and 
strychnine in suitable doses wull also help to restore the saline ingre- 
dients of the blood. Recently subcutaneous injections of human blood 
serum have been employed with good results.

Herpes Progenitalis 

Synonyms : Herpes preputialis ; Herpes genitalis 

Plate 4, Fig. 8 ; and Plate 5, Fig. 9 

The above affection possesses an unusual degree of interest be- 
cause its consideration belongs alike to the dermatologist and genito- 
urinary surgeon. It may follow coitus (as a result of mechanical 
irritation) and it frequently serves as a port of entry for the virus of 
syphilis. It is also prone to develop in male subjects who have had 
gonorrhea, apparently as the result of irritating pathological condi- 
tions in the urethra, vesicles, or prostate. Herpes progenitalis is emi- 
nently a relapsing affection. One attack may be succeeded almost 
immediately by another. 

In the male the little clusters of vesicles appear either on the inner 
aspect of the prepuce and the glans, or on the integument of the penis. 
In the latter case a typical cluster of vesicles is evident as in Fig. 8. 
These behave exactly like herpes on the face and the nature of the 
group of shiny vesicles is manifest. On a patient with no prepuce, 
or only a short one, the mucosa resembles skin and the vesicles behave 
in the same manner, but in subjects with long foreskins the vesicles 
occurring on the glans are quickly ruptured and the clinical appear- 
ance is more that of a balanitis. As a rule it is not easy to recognize 
the site of the vesicles in these cases, owing to the edema and retained 
secretion that is often present. 

We know comparatively little about genital herpes in women and 
authorities differ as to its frequency. The labia minora and clitoris 
are the parts most frequently affected although the eruption often 
occurs on the labia majora and adjacent integument, as sho^\^l in 
Fig. 9. In certain cases the vesicles enlarge to a considerable size and 
show a yellowish floor suggestive of a chancroid. These enlarged 
vesicles may also coalesce, so that a large eroded surface results. 
There is an offensive discharge and the itching and burning is often 

11 



intense. The inguinal glands are frequently enlarged and v/aUiing 
becomes difficult. 

Diagnosis 

This should not be difficult in an uncomplicated case, but when the 
vesicles have been ruptured and suppuration has taken place it is not 
always easy to exclude a chancroid. The latter, however, will gener- 
ally show deeper ulceration and a fouler base. Time and treatment 
will also help to clear the question. An attack of herpes is usually 
cured in a few days by the use of mild antiseptic applications, whereas 
a chancroid under the same treatment would increase in size. Auto- 
inoculation of a chancroid is seldom justified, but pus may be scraped 
from the border of the ulcer, fixed and stained, and in the case of a 
chancroid the microscope will show the characteristic bacillus of 
Ducrey. 

Primary syphilis should be readily excluded by the clinical history, 
the absence of induration, and by a negative laboratory report as to 
the presence of the spirocheta pallida. 

A simple balanitis often resembles the condition seen in herpes 
of the prepuce after the vesicles have ruptured, but in the former 
affection there is no history of the presence of previous vesicles. A 
diabetic balanitis is easily excluded by examination of the urine for 
glucose. 

Local Treatment 

The treatment of the lesions of herpes progenitalis is usually as 
efficacious as it is simple. Few cases fail to respond to cleanliness and 
mild antiseptic dusting powders. In male patients the prepuce should 
be retracted and the glans and contiguous mucous membrane cleaned 
with a weak boric acid solution and an application of aristol made 
over the vesicles. If there is infection or ruptured vesicles, it is well 
to use a 50% solution of hydrogen peroxide before applying the aris- 
tol. Other powders that may prove efficient are acetanilid, calomel, 
subnitrate of bismuth, and oxide of zinc. A redundant prepuce should 
be separated from the glans by a strip of gauze or pledget of cotton. 
If there be much edema the patient should be instructed to hold the 
penis in a cup of warm water for several minutes, two or three times a 
day. To hasten the healing of ruptured vesicles, the use of an astrin- 
gent wash is often beneficial. Powdered alum, gr. xx to gr. xxx to the 
ounce of water, makes a very good one. For superficial ulcerations 
the silver nitrate stick may be used. 

12 



Prophylaxis 

Under this caption may be considered treatment designed to pre- 
vent the reguhir or irregular recurrence of the affection. 

First of all, the general health, which in these patients is nearly 
always lowered, should be improved. Tonics containing iron, quinia, 
and strychnia are often beneficial and in certain chronic cases arsenic 
has proved of distinct value. Errors of diet should be corrected and 
careful attention given to gastric and intestinal derangements. Alco- 
holic and fermentative liquors, as well as tobacco, generally act 
prejudicially. 

Patients should be thoroughly instructed in sexual hygiene as the 
congestion of the genital organs following prolonged sexual excite- 
ment is often a prominent factor in the causation of this affection. 
"Wliile it is advisable to have a long tight foreskin removed it must be 
borne in mind that circumcision does not always prevent recurrent 
attacks. Some of the most rebellious cases that I have had under 
observation occurred in individuals who had been circumcised in 
early infancy. In some cases benefit follows the regular passage of 
cold sounds and instillations of argyrol. One phase of the prophylac- 
tic treatment that is rarely spoken of in text-books is the treatment of 
pathological conditions of the seminal vesicles. A number of my 
cases apparently depended upon a chronic catarrhal inflammation of 
the vesicles and treatment directed to the vesiculitis caused a cessa- 
tion of attacks after numerous other forms of treatment had failed.

Herpes Simplex 

Synonyms: Herpes facialis, Herpes labialis 

Plate 5, Fig. 10 

Strictly speaking, genital herpes belongs in this category, but for 
practical reasons it is better to regard it as a distinct affection. 
Herpes simplex may occur in almost any locality as the result of a 
possible nerve injury or irritation. In practice, however, the affec- 
tion is limited to the face — chiefly about the lips and outlying skin. 
Occurring at the junction of the skin and mucous membrane at the 
mouth or nostril it is the familiar "cold sore," which accompanies 
an acute coryza. These forms are extremely common, and are limited, 
as a rule, to a single small cluster of vesicles. Herpes facialis, so 
called, is a cutaneous eruption, not necessarily limited to one area, 
but able to involve a large portion of the face. It is usually associated 
with acute affections like pneumonia and influenza, the "fever blis- 
ters" of the laity, and is not, as has sometimes been thought, any 
criterion of the severity of the disease. The lesions are composed 
of clusters of vesicles, the numbers of both vesicles and clusters 
varying. The clusters are usually grouped together, forming large 
patches. The vesicles appear on a slightly hyperemic base and are 
nearly always attended with pricking sensations and soreness. They 
are naturally minute, but may attain considerable size as if from 
coalescence (hence the popular word blister). The liquid contents 
are absorbed or become desiccated, and a discharge never occurs. 
The disease runs a definite course, lasting a week or ten days, at 
the close of which period a scab is detached. There is considerable 
tendency to recurrence in the same area ; in fact, in the minor forms 
one attack appears to predispose to others. The peculiar nervous 
sensations, the character of the little vesicles and the occasional 
association of slight irritation — for example, the irritation of the 
nostril and upper lip at the outset of a cold — show plainly a nerve 
element in the make up of the affection — reflex or ganglionic. 

14 



Diagnosis 

Extensive facial herpes with much crusting may have to be dis- 
tinguished from other facial eruptions — eczema and impetigo — but 
this should not be difficult. 

Treatment 

The frequent application of spirits of camphor to the lesions will 
relieve the burning and hasten their disappearance. AVhen the crust- 
ing stage is reached ointments are indicated. The following is a good 
one, particularly for herpes labialis: 

IJ Tinct. camphor IlKvii 

Pulv. calamine prep gr. v 

Zinci oxidi gr. vii 

Aquae rosae 3ii 

M. et ft. ungt. 

In the troublesome, periodic form Norman Walker recommends 
the painting of the affected area with argent, nitralis (gr. xx) spr. 
a'ther. nitrosi (gi). This he believes will often increase the intervals 
between attacks, and will in time bring about a cure.

Herpes Zoster 

Synonyms: Shingles, Zona 
Plate 6, Fig. 11; and Plate 7, Fig. 12 

Herpes zoster differs from all other acute affections of the skin in 
that it is a secondary manifestation, due to an acute inflammation of 
the nerve fibers which are distributed in the affected area. There are 
few cutaneous affections of which the mechanism is so simple, even if 
the ultimate causal factors are obscure. The disease has points in 
common with herpes simplex, in which the terminal nerve-filaments 
are doubtless involved, but not the main nerve-trunks. In both herpes 
simplex and progenitalis, clusters of vesicles arise rapidly on a hyper- 
emic base with unpleasant tingling and pricking sensations; but in 
zoster the pain may be extreme — neuralgiform — and is associated 
often with intense hyperesthesia. In some cases the pain antedates 
the eruption by several days. Like simple herpes, zoster runs a 
definite course and is self-limited. The eruption requires about two 
days for its evolution, and on an average a week elapses before it 
begins to subside. The vesicles, as in herpes simplex, do not rupture 
and dry into scabs. Unlike the former they may leave permanent 
scars. 

Although herpes zoster is almost necessarily unilateral, bilateral 
cases have occurred. In the great majority of cases the affection 
occurs on the trunk or region of the eye. The areas that may be in- 
volved vary greatly in extent. In zoster of the ear, an affection not 
much discussed by dermatologists, a few vesicles only may suffice for 
the expression of the disease. Conversely in zoster of a lower extrem- 
ity the area affected may be very extensive. Differences also occur 
based on the severity of the case. Thus in a given area there may be 
only a few vesicles localized at one point or the entire area may be 
the seat of clusters. 

Zoster of the face and head seems more severe than elsewhere, 
because for some reason acute trophic lesions may accompany the 
ordinary phenomena. Naturally in zoster involving the eyeball a few 
vesicles on the cornea may result in opacities ; but there is added a 

16 



Plate 6.

cortain pernicious quality to tlie eruption by reason of wliicli tlio eye- 
ball may be destroyed. Deep scars often remain on the forehead, due 
perhaps in part to diminished resistance of the tissues. For the same 
reason the vesicles may become infected, and as a result of thrombo- 
phlebitis fatal intracranial mischief may be set up. 

Zoster affecting the face may be accompanied by vesicles on the 
mucous membranes and trophic alterations in the teeth. Contrary to 
what one would expect, the motor component is almost negligible in 
zoster. Cases of paralysis, some permanent, have been recorded ; also 
isolated cases of spasm. 

Eiiologj/ 

It has been conclusively demonstrated by Head that the affection 
is due to a hemorrhage or other pathological change in a posterior 
spinal ganglion and that with almost unfailing regularity the location 
of the eruption is determined by the cutaneous distribution of the 
nerve-fibers that i)ass through the affected ganglion. In regard to the 
factors which determine the nerve-lesion, these seem to be legion. 
The most important appears to be a specific conununicable virus 
which often causes small epidermics. In this type of zoster we see 
malaise, fever and other phenomena observed in acute infectious 
diseases. Generally speaking, any circulating poison in the blood, 
any form of reflex irritation and traumatic influences (as in herpes 
simplex) may be able to produce zoster; whence some would distin- 
guish between true zoster and zosteroid eruptions. "Well recognized 
indi\'idual causes are arsenic (it frequently follows injections of 
salvarsan), carbon monoxide, and malaria. It is not uncommon in 
tuberculosis. The evidence in support of reflex causation seems 
weakest. 

Diagnosis 

The earliest vesicles of zoster, associated as they usually are ^^'ith 
pricking sensations, are sometimes mistaken for local effects of bites 
or other traumatism. Typical herpes zoster should hardly be con- 
founded with any other eruption because of its unilateral distribution 
and peculiar subjective sensations. Zoster on the face may of course 
be confused with herpes facialis and conditions resembling it. In se- 
vere cases, however, it would be more likely to suggest erysipelas. 
The latter, however, has constitutional s>nni)toms, is bilateral, infil- 
trated, and has the characteristic sharply defined margin. Zoster 
may run an abortive course and these cases are sometimes misleading. 

17 



Prognosis 

Certain features of zoster may bring up the question of prognosis, 
although generally speaking a mild self-limited affection can have but 
one prognosis. If the affection occurs in connection with a neuritis 
or neuralgia the pain may persist and even increase. The pitting 
about the face and head may be deep, and the practitioner may well 
be on his guard in calling the affection a trifling one. This obtains 
even more strongly in zoster ophthalmicus, in which the cornea may 
be rendered opaque with resulting blindness. The fact must not be 
lost sight of that zoster has been known to end in gangrene. 

Treatment 

Some authors, who evidently confound the predisposition with the 
actual disease, advise the general regimen for neuralgia, such as nerve 
tonics (arsenic, iron, quinia), coupled with change of climate neces- 
sary for all gouty and malarial subjects. Since zoster seldom recurs, 
it is difficult to understand how this regimen could influence an acute 
self-limited affection. We can only interpret this management as 
something directed to the underlying condition of which the disease 
is a transient expression. 

The pain may be the chief cause of the patient's visit, and as pain 
is almost always in evidence the practitioner should be prepared to 
mitigate it. Among anodynes a hypodermic of morphine close to the 
area involved is usually effective, but satisfactory results may often 
be attained by the use of acetanilid or phenacetin. A remedy upheld 
for many years is galvanism along the affected nerve to the extent of 
five milliamperes with a ten-minute exposure. Measures well spoken 
of are blisters over the part of the spine at the point of exit of the 
sensory nerve, and mild freezing, with ethyl chloride or dry cupping, 
at the same point. Of the numerous local applications recommended, 
not much is to be expected ; they may all be summed up under pro- 
tection and immobilization, which may be effected by dusting the area 
heavily with talcum powder and then applying a tight bandage, the 
inside of which is also thickly coated with the same powder. Such a 
dressing, which need be changed but once, will usually suffice for the 
local treatment of an ordinary case. Care should be taken not to rup- 
ture the vesicles so as to prevent the possibility of infection with sub- 
sequent scars.

Pompholyx 

Synonyms: Dysidrosis, Clieiro-pompholyx 

Plate 7, Fig. 13 

This is a purely topical affection, limited to the extremities and 
chiefly the palmar and plantar aspects. The fingers are commonly in- 
volved, and the eruption is usually sjTnmetrical. The lesions consist 
of vesicles and bullse, the latter resulting from distention and coales- 
cence of the former. These lesions tend to appear in clusters, and are 
quite deeply seated, so that they have been compared to boiled sago 
grains. If not too crowded, there may be no coalescence to form 
bulla;, and the enlarged vesicles may disappear from absorption of 
their contents. If absorption does not occur, the contents become 
cloudy and at times purulent; when coalescence takes place actual 
bullap may form or the entire epidermis may exfoliate. The eruptions 
appear in crops or more or less continuously, and after a variable 
interval, perhaps of several months, spontaneous recovery occurs. 
The affected parts usually show poor circulation and excessive per- 
spiration, and the eruption is usually attended A\nth burning and 
itching. There is more or less absence of type, so that cases show 
considerable individuality. There is some reason to believe that 
abortive forms, limited to a few transitory vesicles, may not be as 
rare as the disease itself is believed to be. 

Etiology 

The earliest observers had no doubt that the affection represented 
a disorder of the sweat-glands and that the vesicles were simply re- 
tained perspiration— whence the name dysidrosis. This error— for 
an error it was — was most natural, for the affection is limited to 
areas where the sweat-glands are both large and numerous, and the 
patients, as a rule, showed habitual hyperidrosis of the extremities. 
That the lesions are not mere retention cysts containing sweat was 
soon made evident. This fluid is pure blood serum, and pomphoh-x, 
while not strongly resembling a weeping eczema, is more closely 

19 



allied to it than to any other known affection. Little is known of 
the cause; but the disease is common in women during the repro- 
ductive cycle, and nervous and psychic influences are often in evidence 
in relation to an attack. 

Diagnosis 

Since pompholyx is a local affection limited to certain areas, diag- 
nosis should not be difficult. The indirect method of exclusion may be 
necessary in certain atypical cases. The only affections which might 
cause confusion are acute vesicular eczema and certain forms of 
localized dermatitis venenata, notably ivy poisoning. Some confusion 
has arisen in past years between pompholyx and pemphigus ; this is 
due to the common bullous character and similarity in sound of the 
names — also perhaps to the fact that pemphigus is sometimes located 
on the extremities. The two conditions, however, should never 
occasion any confusion in practice. 

Prognosis 

A case of dysidrosis is often tedious, but the individual attack will 
undergo involution sooner or later. The unfavorable element is con- 
nected with recurrence, which is likely to occur under precisely those 
conditions which cannot be foreseen or prevented. 

Treatment 

The best results, both in arresting an attack and preventing a re- 
currence, will come about through internal medication. Arsenic fre- 
quently appears to have considerable control over the eruption, and 
arrests its development. Other drugs of value are iron, quinia, 
strychnia, and the hypophosphites. The external applications should 
consist of soothing and drying applications. Relief is generally 
afforded by Lassar's paste or by Hebra's diachylon ointment. Here 
is the formula of the latter:

Fig. 14. Impetigo contagiosa. 



Impetigo Contagiosa 

Plate 8, Fig. 14 

This affection, highly contagious, often disfiguring and well cal- 
culated to cause alarm, is, in reality, a very benign, superficial malady, 
which would demand but little attention were it not so liable to con- 
fusion with other and much more serious dermatoses. It yields 
to the simplest treatment, and even if left to itself would recover 
within a comparatively short time, despite the fact that it is auto- 
inoculable, and that many of its lesions doubtless originate in this 
manner. The name impetigo is a decided misnomer, as tliis implies 
that the affection is essentially pustular. As a matter of fact the 
essential lesions are vesicles and bullfc, the contents of which quickly 
become turbid from leucocytes ; so that when rupture occurs and the 
fluid evaporates, thin crusts are formed which adhere rather closely 
to the skin. These, when detached, show a slightly reddened integu- 
ment, which exhibits a slight tendency to ooze at the sites of the 
original vesicles or bulls'. While this affection may occur in a 
typical form, and spontaneously, we also see cases in which it 
apparently complicates some other affection in which scratching and 
abrasions are features. It is not uncommonly determined by vacci- 
nation; and in pediculi capitis in children it is so closely associated 
by authors Avith the vesiculo-pustular outbreaks on the neck, etc., 
that some have gone so far as to state that pediculosis is one of the 
most common causes of impetigo contagiosa. In ordinary cases of the 
latter they would always look for pediculi. A point not sufTicioiitly 
discussed is the relation of impetigo to scabies. Some claim that the 
frequent location of the affection about the lips and nostrils may 
have some bearing on the secondary infection of a herpes simplex. It 
will thus be seen that impetigo may behave as a primary or secondary 
affection. 

It is commonly stated that impetigo contagiosa is due to ordinary 
pus exciters — staphylo — and especially streptococci. It is interesting 
to note that the secretions of tliese lesions are being continually in- 

21 



oculated, but that local and general infection never appear to develop 
even in abortive forms. In some cases, however, where the out- 
break is extensive, we note a mild general reaction with fever and 
adenopathy. 

Impetigo contagiosa is very largely an affection of childhood, at- 
tacking chiefly the dirty and unkempt, in whom it pursues a fairly 
typical course. But it is of much greater significance when it attacks 
adults, especially those who are of neat habits. Here its behavior 
is often highly atypical, and the sudden appearance of lesions on the 
face and throat usually leads the patient to believe that barber's itch 
or syphilis, or some other more or less reprehensible malady, has been 
contracted. Petty epidemics sometimes arise in coimection with 
public swimming baths. 

The sole lesion, in the vast majority of cases, is the flattened 
crust, which may be gray, yellow, or broA\Ti. This occurs by pref- 
erence on the exposed surfaces — face, neck, hands, wrists, etc., and, 
in children who go barefoot, on the feet and legs. But no one 
should rest satisfied with this picture, for lesions may not only 
appear in almost any locality, but may exhibit a bizarre behavior. 
Thus Scliamherg illustrates a case in which the lesions occupied the 
groins and axillae, and exhibited a cireinate, serpiginous progression. 
If we bear in mind that the affection can be grafted upon other 
conditions we must be prepared for much variety and ambiguity in 
expression in selected cases. 

Etiology 

In the absence of any specific cause Bocl:hart's view that it may 
be caused by a variety of germs which exert a very superficial action 
may be accepted for the present. The lesions, as becomes vesicles 
and bullae, occupy the space between the horny and mucous layers, 
which accounts for the fact that the latter, the corium, lymphatics, 
etc., escape all serious implication. 

Diagnosis 

We have to exclude eczema, and as impetigo may be grafted upon 
the latter the differentiation is not always easy. Results of treatment 
in eczema, as in other maladies, must decide, for impetigo yields very 
promptly to treatment. There should be no confusion with sycosis 
of either type, because there is no involvement of the hair-follicles. 
Exclusion of syphilis is sometimes difficult, but as good a diagnostic 
procedure as any is the simple detachment of the crusts which demon- 

22 



strates the entirely superficial character of the lesions of impetigo 
contagiosa. 

Treatment 

The affection is perhaps more easily cured than any other of 
its class. Hence tliere is no need to use applications in any notable 
concentration. If there should be any dilhculty in detaching the 
crusts they may be softened with borated vaseline. The exposed 
surface sliould tlion be cleansed -with an antiseptic solution, and if 
the eruption is general an antiseptic bath may be given. The best 
application for the lesions is an ointment of white precipitate. The 
usual strength of thirty grains to the ounce is unnecessarily high, and 
wliile comparatively harmless, is less effective than a two per cent, 
ointnient. An efficient formula is :

Hydroa Vacciniforme 

Synonym: Hydroa aestivale 

Plate 9, Fig. 15 

This is an affection of cliildliood and adolescence, hence in part de- 
velopmental, which tends to appear in successive summers. It may be 
papular, but is usually vesicular and, like vaccine vesicles, leaves pits. 

It is very largely limited to males. Since it occurs by preference 
on exposed surfaces it presents almost the same causal factors as 
freckles. It is, moreover, a familial affection in certain cases. The 
lesions come out somewhat like a rash, with some general disorder and 
local sensory disturbance — burning, or more rarely itching. 

In a well-marked case the nose, cheeks and ears are first the seat 
of a diffuse or circumscribed redness. As a rule, small vesicles, the 
largest pea-sized, appear on this basis. The considerable size of some 
of the vesicles is responsible for the term hydroa. Coalescence is 
rare, but blebs have sometimes formed. The contents of the vesicles 
are at first clear, then turbid. The majority of them undergo distinct 
umbilication, after which crusts form and come away, leaving small 
scars. 

The vesicles may appear in several successive crops during the 
summer, at intervals of several weeks ; or, more commonly, there is a 
more or less continuous evolution of them. This, with the annual re- 
currence, will tend in the worst cases to very extensive pitting of the 
nose and other localities. There are numerous atypical forms. The 
affection may be abortive and may not reach the vesicular stage ; or it 
may appear in cool weather and in adults. In some cases there may 
be considerable scattered eruption on the covered regions. 

Etiology 

Aside from the predisposition the sole causal factor appears to be 
the summer sun, and wind. The pathologic process is an inflamma- 
tion of the papillary layer of the corium. 

24! 



Plate 9. 




Fig. 15. Hydroa vacciniformis, 



Diagnosis 

Several somewhat sinxilar conditions liave been described, and it is 
a question whethei- or not they are simply atypical forms of hydroa 
vacciniforme. Unna's hydroa puerorum shows no tendency to a sea- 
sonal incidence and does not lead to scarring. Summer prurigo is a 
papular itchy eruption, diffused over the integument. 

Treatment 

The face should be protected from the chemical rays of the sun, 
and most authorities reconmiend the wearing of orange or red or 
dark-colored veils. Theoretically, this may be good prophylactic 
treatment, but it must be remembered that our patient is a small boy 
at play with his fellows and, well, a small boy is a small boy the world 
over. The application of a thick lotion containing calamine, mag- 
nesia, and zinc would be more practical and quite as effective. Nor- 
man Walker suggests that in mild cases it is often best to explain the 
nature of the disease to the parents, and tell them not to worry too 
much about it.

Pemphigus Vulgaris 

Plate 10, Fig. 16 

Pemphigus is a term that has been applied to a variety of bullous 
affections, certain of which have but little in common beyond the 
presence of the bullae themselves. Since any intense inflammation of 
the skin, however produced, may give rise to bullae, it is necessary 
first of all to distinguish between pemphigus proper and the pemphi- 
goid eruptions, especially such as dermatitis herpetiformis, urticaria 
bullosa, etc. It must not be forgotten that in nearly all vesicular af- 
fections bullae may result from coalescence, sometimes as a rule, some- 
times only exceptionally. The presence of bullae under such circum- 
stances may be obscured by their rapid rupture, or by the drying of 
the turbid contents into crusts or scabs. Thus some writers affect to 
believe that impetigo contagiosa measures up to the standards of true 
pemphigus. There are also eruptions in which the lesions are inter- 
mediate in size between vesicles and bullae which are termed hydroa, 
and some of which appear to present no essential differences from 
pemphigus. Finally, the affection known as pompholyx has often 
been confused with pemphigus. 

It is therefore highly important to determine not only whatever 
does not belong to true pemphigus, but to give to the latter all the 
positive attributes possible. First of all pemphigus must be regarded 
as a rare and a chronic affection. Its essential primary lesions are al- 
ways bullae at the very outset. They must arise either upon normal 
skin, or at most on skin which is slightly reddened. They have no 
limited areas of distribution, but may appear on almost any portion 
of the integument, and save in the universal forms, independently of 
any local or traimaatic factors. The fact that the mucosae suffer with 
the skin in severe cases also shows plainly the endogenous nature of 
the malady. Several well-defined types of pemphigus exist, but to 
what extent these represent separate affections or mere varieties or 
degrees of intensity cannot be determined. 




Plate 10. 



p;rr \ f\ Pf»»iit-vhi(Tii< \_iilnfiiriQ 



Pemphigus vulgaris is appropriately named, as it is the most 
coimnon type of the alTection. It is a chronic affection only in the 
sense that new lesions continue to appear. They do not, however, 
change their type, for the bulla; in a long-standing case do not differ 
from those of the first outbreak. In the main the lesions appear in 
crops, with intervals of latencj' ; but as in all diseases which manifest 
themselves by successive outbreaks, we may at times encounter serial 
or overlapping cases in which the surface appears to be constantly 
covered with bulla>. In these cases there is usually some marked con- 
stitutional involvement and the prognosis is grave, altliough death 
may not be due directly to the eruption, which may cause of itself 
but little general disturbance. Even if the single first outbreak is un- 
usually thick or confluent, the prognosis is much more serious than 
when it is sparse. The bulhe are therefore rather an index of some, 
perhaps grave, general state than a direct cause of death, which may 
be due to the most varied causes. As will be seen later, the two other 
forms of pemphigus appear to be able to destroy life directly, and it 
is no doubt true that pemphigus vulgaris may sometimes pursue a 
similar course. It appears justifiable to speak of benign and ma- 
lignant penipliigus \mlgaris. 

Under ordinary circumstances, or, as we may say in benign cases, 
a crop of bullae requires one or two days for its evolution and one 
or two weeks for its involution. Sooner or later a new outbreak ap- 
pears, followed by others, which are less and less pronounced, until 
after some months the process is arrested. 

Etiology 

Nothing is known of the intimate nature of pemphigus vulgaris, 
and even the conditions under which it occurs show little uniformity. 
Several causal factors are vaguely evident. One is a neurotic ele- 
ment, suggesting that in miscellaneous affections of the central and 
perhaps the peripheral nervous system there may be a lowered re- 
sistance of the skin to noxa; of various kinds. Another element is the 
frequent suspicion of contamination from human or animal disease 
products ; in some cases the causation appears to be septic infection 
of the ordinary sort. Autotoxemia, including the intestinal tj-pe, is 
a third factor often recognizable. 

Diagnosis 

Pemphigus vulgaris requires differentiation only from the other 
types of pemphigus and from such pemphigoid eruptions as eryth- 

27 



ema naultiforme, urticaria bullosa, and dermatitis herpetiformis. 
This should not be difficult after a given case has been under observa- 
tion for some time. 

Prognosis 

As a rule, the greater the freedom from local and general com- 
plications of any sort and the more scanty the eruption, the better the 
outlook, which is, under other conditions, always serious. 

Treatment 

Arsenic has an unquestionably specific action on pemphigus vul- 
garis, but whether it can save life in the grave cases is open to 
doubt. It is often combined with strychnia and quinia and other 
tonics. The patient should be studied thoroughly and be given the 
advantage of any improved hygiene. Locally, the management is 
practically that of intensive moist eczema — the same medicated baths, 
lotions, etc. Hehra, many years ago, treated pemphigus with the con- 
tinuous bath, and this resource is well calculated to make the patient 
as comfortable as possible under the circumstances. The same end 
may be attained by a system of dressings, as in the case of universal 
eczema, severe burns, etc.

Fig. 17. Pemphigus foliaceus. 



Plate 11. 



Pemphigus Foliaceus 

Plate 11, Fig. 17 

In this form of pemphigus, as in pemphigus vulgaris, new buUffi 
constantly appear; but since the areas denuded show no tendency 
whatever to heal, the disease picture differs extremely from that of 
the ordinary form. Pemphigus foliaceus may develop from pem- 
phigus vulgaris or may appear de novo. "VNlien the bulla? do not 
rupture at once, they coalesce, and considerable quantities of sero- 
purulent fluid collect and, follo^\^ng the law of gravitation, form 
characteristic flaccid sacs, instead of tense, rounded bulla;. The ulti- 
mate tendency of the disease is to denude the entire corium. This is 
effected not only by the formation of new bulljp, but by burrowing at 
the periphery of those already formed. Upon the excoriated surface 
feeble attempts at epidermization are seen side by side with the for- 
mation of small abortive bulte in the imperfectly generated epidermis. 
The discharge also dries upon the denuded surface in the form of 
crusts having a sort of tile-like arrangement from the development of 
fissures. These dried crusts are shed as a result of the oozing be- 
neath and this phenomenon gives the disease its name. Ultimately 
nearly the entire integument A\dth the visible mucosa; may become 
involved, but death often occurs Avhile much of the skin is still intact 
along with the mucosae. In advanced cases one of the most distressing 
symptoms experienced by the patient is a sensation of constant cold 
and chilliness. The nails and hair are not necessarily lost, but the 
former become deformed and the hair shed abundantly. 

Etielogy 

The cause of the disease is unknown. Some authorities, however, 
believe that it is due to the presence of a toxin circulating in the blood 
and that the cutaneous manifestations are secondary. 

Diagnosis 

"When the mucosa; are involved pemphigus foliaceus is automat- 
ically differentiated from any of the forms of universal dermatitis. 

29 



There are, however, cases so mild that one would hardly be likely 
to associate them with so grave a condition. The flaccid bullae, and 
the excoriated surfaces which refuse to heal are sufficient for diagno- 
sis, but since the lesions at first may respond to the use of arsenic, 
the practitioner may regard the affection as ordinary pemphigus. 
Ultimately the disease is unmistakable and the odor is so characteris- 
tic that a diagnosis can often be made from a considerable distance. 

Prognosis 

This is always grave. 

Treatment 

There is no loiowTi efficacious treatment and considering the grav- 
ity of the disease any rational form of experimental therapy is fully 
justified. Some of the symptoms may be relieved by local treatment 
similar to that employed in pemphigus vulgaris. 

Attempts should be made at active disinfection of the exposed 
surfaces, for at present we do not know how much of the fatal ele- 
ments in pemphigus may be due to the absorption of toxic matter.

Fig. 18. Pemphigus vegetans. 



Pemphigus Vegetans 

Plate 12, Fig. 18 

This affection, like pemphigus foliaceus, is best described inde- 
pendently ; for despite the fact that it is a bullous dermatosis, it was 
originally not classed as pemphigus, and it is largely a matter of 
opinion even now as to Avhether it should be so regarded. There is 
no doubt, however, that it shades into the different forms of pem- 
phigus. Exceptionally pemphigus vulgaris and pemphigoid affec- 
tions may assume a vegetating character. In the typical disease, 
however, pemphigus vegetans is a distinct affection from the outset. 
It tends to attack moistened cutaneous surfaces and the visible 
mucosjE ; and to this peculiarity is to be attributed the fact that the 
excoriations resulting from the maceration of the skin tend to form 
condyloma-like excrescences. The affection therefore markedly re- 
sembles the so-called moist syphilides ; and as a matter of fact it was 
originally confounded with syphilis, even by such authorities as 

Kaposi. 

This resemblance to syphilis is so pronounced that an account of 
pemphigus vegetans is largely a matter of differential diagnosis. The 
disease is such a rarity tliat generalizations are hardly wise ; but its 
most pronounced differential feature in all typical cases is failure to 
respond to treatment of any sort. A lesion of pemphigus vegetans is 
to all extent and purposes a lesion which is semi-malignant. It has 
no tendency to heal nor can it be made to heal. In many cases there is 
an added tendency for the lesions to generalize from the moist to the 
dry surfaces. In these generalized eases there is an undeniable re- 
semblance of the lesions to those of ordinary pemphigus. The vege- 
tating feature, however conspicuous, is perhaps (like the continuous 
exfoliation) merely a detail, as is the case in syphilis. Death in 
certain cases if not in the majority is due to some intercurrent or 
pre-existent affection, but it frequently occurs from the disease it- 
self, possibly as the result of exhaustion. One of my patients, a 
woman of sixty, died three months after the appearance of lesions in 
the mouth. She was well nourished and at autopsy an experienced 

81 



pathologist was unable to discover any visceral lesion that would in 
any way account for death. 

Etiology 

Aside from the fact that most of the victims have been middle- 
aged women, some of whom had previously contracted syphilis, but 
little can be said under this head. There is no apparent connection 
with gestation or with the nervous system. In a very few eases the 
disease may have represented a septic infection, which lends some 
color to the hypothesis of a crypto-genetic sepsis. Histologically the 
vegetating lesions present a picture very much like that of syphilitic 
condylomata. 

Prognosis 

The course of the disease is much like that of pemphigus foliaceus. 
In typical cases the patient is almost sure to succumb to exhaustion 
within a year, while some perish as early as two months. Cases of 
reported recovery are usually found to be those which were distinctly 
atypical, either because grafted upon ordinary pemphigus, or some 
pemphigoid eruption, or because the lesions showed no tendency to 
generalization. 

Treatment 

Although arsenic is of little or no value in this disease, the employ- 
ment of salvarsan is worthy of trial. Mercury and potassium iodide 
do not appear to retard the progress of the disease. 

Aside from the general desiccating and soothing remedies in com- 
mon use in similar cases and the continuous bath, the only rational 
measure ever introduced in harmony with progressive therapeutics 
is disinfection, which is performed somewhat as in extensive burns. 
On account of the superficial character of the lesions mild measures 
may suffice, such as solutions of hydrogen peroxide, potassium per- 
manganate and Labarraque's solution in proper dilution. These may 
be used in spray form or on saturated cloths. Carbolic acid solutions 
have been advised whenever the danger of absorption can be 
minimized.

Pemphigus Neonatorum 

Plate 13, Fu;. 1!J 

It is almost universally conceded that tins is a pemphigoid condi- 
tion having absolutely no connection -with the pemphigus proper. It 
has several sharply defined clinical characteristics. First it attacks 
the newly born only; second, it is contagious, and tends to occur m 
epidemics in maternity hospitals; third, it is dependent in some man- 
ner on conditions -svhich favor septic infection, and is often associated 
Avith septic conditions either in the infants themselves, the puerperal 
Avomen, or the attending physician and nurse. Thus it may be re- 
garded as one member of a group disease — acute sepsis of the newly 
born, which comprises such other members as umbilical sepsis, septic 
coryza, septic pneumonia, buccal sepsis, etc. Pemphigus is, in fact, 
by no means the sole type of cutaneous sepsis of the newly born, for 
under this head are commonly placed R itter's d isease (dermatitis 
V exfoliativa neonatorum) ; ecthyma (some forms of which cause gan- 
)^~grene) ; multiple subcutaneous abscesses, etc. Even erysipelas neona- 
torum has been placed in the same category. Associated with all 
these manifestations w^e find the ordinary pus-exciting microorgan- 
isms, which are commonly held responsible for puerperal sepsis in 
the mother. 

The mechanism of infection presents the same obscurity in the in- 
fant as in the mother. The pyogenic microorganisms are no doubt in- 
oculable, for adults sometimes contract bulUc from the children. 
But if that were all the disease signifies, it would only be plain im- 
petigo contagiosa. The latter, as stated elsewhere, is not knowTi to 
cause constitutional infection even under aggravated conditions, and 
is never regarded as in any sense septic. In pemphigus neonatorum, 
however, a large proportion of the children are already septic or soon 
become so. If the bullse are regarded as primary lesions, some consti- 
tutional reaction should occur, but that they should form a port of 
entry for germs is not in accordance with analogy. It is more likely 
that cachectic or premature children, while specially prone to contract 
the eruption, in reality perish from other causes; or that some more 
severe form of sepsis attacks the child at the same time. That the 
bullje are metastatic is not to be believed, for skin lesions, secondary 
to knoAVTi sepsis, are very rare and behave in a very different manner. 

83 



To understand better a problematic affection of this sort, the 
study of an individual epidemic is instructive. In tlie fall of 1906 
twenty-seven babies were attacked in the Lying-in Hospital of the 
City of New York. The great majority developed the affection from 
the fourth to the seventh day. Nine babies died, but in only six 
cases could it be held that pemphigus caused death, and in none was 
there evidence of general sepsis. The more severe as a rule the 
eruption, the graver the prognosis ; in other words, the eruption fur- 
nished an index of severity, arguing the existence of a strong predis- 
posing element. The absence of fever in some of the worst cases 
seemed to indicate a profound toxemia of the sore sometimes seen in 
rapidly fatal diseases. In certain cases contagion could be showm. 
Staphylococci could be cultivated from the bullae. None of the 
mothers were septic. H. J. Schwartz, who describes the preceding, 
is inclined to believe that toxins formed by the local suppuration 
caused death in the fatal cases, and it is possible that in this as in 
similar maladies a toxic substance is produced in the skin analogous 
to that now known to be the essential cause of death after burns. 
Such cases at least suggest the possibility of a fatal component which 
has no connection with sepsis. At the other extreme are innocent 
cases, in all respects resembling impetigo contagiosa, which tend to 
appear about the navel only (periumbilical pemphigus). In certain 
cases this mild type becomes the starting point for the ordinary 
severe form. 

The eruption of pemphigus neonatorum in typical cases appears 
within the first fortnight of life, and without any regular sequence. 
The blebs may be few or many, and in the worst cases become con- 
fluent in certain localities, denuding large quantities of skin. 

Diagnosis 

This shoidd give no trouble. The usual proof is secured by culti- 
vation of one of the pyogenic cocci from the serum of the bullse. 

Treatment 

But little can be said under this head. The infant should be iso- 
lated and placed under all available hygienic conditions. The bullae 
should be punctured and treated with soothing antiseptic dressings. 
In severe cases, however, local treatment is of little avail. Too much 
stress cannot be laid upon the necessity for early and complete isola- 
tion, as the contagious nature of the disease is now fuUy recognized.

Dermatitis Herpetiformis 

Synonyms: Duhring's disease; Hydroa herpetiforme, Pemphigus 

pruriginosis 

Pkite 13, Fig. 20; Plate 14, Fig. 21 

This affection was first described as such by Duhring, but it was 
evidently familiar to many of his predecessors under other designa- 
tions. It is a highly multiform affection, and one of the commonest 
features of the eruption is the presence of clusters of herpes-like 
vesicles. It may present any ciita-uMms losinn s;ivc ulceration, and 
sooner or later is followed by tl'ij) pigmentation. 

The great possihUi-tlcs i'or dil'lVronce in type in individual cases 
made it a difficult disease to describe, and tliis probably accounts for 
the delay in its recognition as a clinical entity. 

In young children it may be wholly v esicular or bullous ; and in 
some of the worst cases in adults the lesions may consist of e^r^^jepaa- 
tou s patch es and papules or vesicopapules. As a rule c onsecutive at - 
t acks present flie same lesions as the first outbreak, so that some 
would divide the disease up into several distinct types. Itching is said 
t o be most intense during the evolution of an outbreak. According as 
the outbreaks succeed one another rapidly or with long pauses, the 
appearance of the case ^\•ill vary. In the former case it is more 
likely to be generalize d, as in the opposite instance many lesions will 
disappear. When the lesions do not proceed beyond the erythematous \ 
stage the eruption is said to resemble greatly erythema multiforme 
when that affection is generalized. 

The question naturally arises as to whether there are any charac- 
teristics which belong especially to this one disease. Is there any- 
thing characteristic of the individual lesions? The large vesicles and 
bullae show peculiar outlines. Instead of being rounded or oval they 
are~angular, polyhedral, elongated and in general show great irre- 
gularily. They are also grouped closely together and otherwise re- 
semble groups of herpes vesicles. The groups, however, are often 

35 



very large — often as large as the palm of the hand, and even occur in 
large sheets. Then, again, a large portion of an entire limb may be 
studded with more or less discrete lesions. As with pemphigus, the 
mucous membranes may sutler. It can hardly be claimed that there 
are any true localities of preference. Like those of pemphigus, its 
lesions may appear almost anywhere. 

Etiologj/ 

The same neurotic element is present here that we have already 
seen in pemphigus. Also the autotoxic and septic factors, and it is 
highly probable that the neurotic element may depend on the presence 
of a toxin in the blood. Eosinophilia isjnyariably iiresent, as well as 

^ , indicanuria. 

(^ Histologic study throws no light on the nature of the disease. 

Diagnosis 

When first seen, and especially during the early outbreaks, a diag- 
nosis is often difficult, because the multiform nature causes it to simu- 
late so many other conditions. The diagnosis is often left open until 
the case can be studied thoroughly. In the erythematous and papulo- 
vesicular stages, the affection is readily confused with eczema or ery- 
thema multiforme, some authors to the contrary notwithstanding. 
Intense itching, refractoriness to treatment, occurrence in suQfiessive 
cro£s_and marked pigmentation causTsuspicion of dermatitis herpeti- 
formis. However, if the characteristic vesicles, bullae or pustules are 
' present, the correct diagnosis is at once suggested. 

Prognosis 

This should be guarded, as the disease is essentially a chronic one. 
Still, many cases improve notably, doubtless as a result of general 
treatment. 

Treatment 

In a persistent disease like dermatitis herpetiformis, hygienic 
measures are of great importance. Everything possible should be 
done to relieve or avoid strain upon the nervous system. Best, free- 
dom from work and worry, and particularly a change of surroundings, 
are indicated. Articles of diet which are prone to cause fermentative 
changes in the intestines, thereby increasing autointoxication, should 
be interdicted. Internal medication should be directed chiefly toward 
improving the patient's general health. Tonics such as strychnia, 

86 



i)C 



V- 



quinia, phosphorus, iron and cod-liver oil, may be used. Of all 
remedies, however, arsenic, judiciously administered, is the most 
valuable. It acts almost as a specific in some cases, particularly those 
offi^jvesicular or bullous type. The dose should be increased grad- 
ually until the disease shows signs of yielding, or the well-recognized 
symptoms of arsenical toxemia appear. The prolonged administra- 
tion of arsenic is not to be endorsed, and its ability to promote 
epithelial growth should be kept in mind. Crocker prefers salicin to 
arsenic, and recommends that it be given three times a day in doses 
of from fifteen to thirty grains. Potassium permanganate in one- 
grain doses, in capsules, taken after meals, was of apparent benefit 
in a number of my cases. 

Locally, any of the antipruritic and antiphlogistic applications 
may render aid. For the pruritus, solutions of ichthyol, potassium 
permanganate, or liquor picis alkalinus are of considerable value. 
The following lotion is particularly serviceable in extensive eruptions 
■ftdth a good deal of inflammation :

Ointments, as a rule, are of less value, althoiigh good results are 
generally obtained from the use of mild sulphur ointment, as first rec- 
ommended by Buhring himself.

Urticaria 

Synonyms: Hives, Nettle rash 
Plate 15, Fig. 22; Plate 16, Fig. 23; Plate 17, Figs. 24 and 25 

This affection must be regarded in a twofold manner. First as 
an innate peculiarity of certain skins, in virtue of which wheals may 
be produced at a point of irritation. To a certain extent this is not 
a peculiarity, for it resides in all skins. Thus the mosquito, bedbug, 
body louse and other insects produce wheals in all or nearly all by 
their bites. In some individuals lesions are produced by contact with 
jelly-fish. The point of a hypodermic or of an electric epilating 
needle very often causes a small wheal. A high, specialized degree of 
this behavior is seen in urticaria factitia and dermographism. These 
manifestations may be produced at will in some subjects. Thus 
whipping with nettles will bring out a crop of wheals, and by dermo- 
graphism is meant that artificial wheals may be determined in lines, 
curves, etc., so that writing may be produced. Other skins behave 
in this manner only during an acute general outbreak of urticaria. 

Secondly, urticaria must be regarded as an acute generalized 
dermatosis of internal origin, of the exanthem type, characterized 
by the evolution of evanescent white or reddish wheals, during which 
there is much subjective disturbance — bitching, burning, etc. Attacks 
may succeed one another in crops. The entire skin and visible mu- 
cosae may be involved, and it is highly probable that an analogous 
disturbance occurs in the viscera. 

There are numerous types of this affection. In the simplest and 
most familiar form there is a single crop of wheals which comes 
and goes in a few hours, the lesions being of pea or bean size; or 
the evolution may be slower and somewhat irregular, so that wheals 
are in evidence for several days. In rare instances the evolution 
of wheals is almost continuous, although the individual lesions come 
and go rapidly. The condition is then called urticaria chronica. In 
certain eases the wheals are represented by small papules closely ag- 
gregated. While these manifestations are usually comprehended 

88

under urticaria factitia, they may occur spontaneously, as a result of 
some internal condition. They are then largely peculiar to the irri- 
table skins of children and may be disseminated over the liml)s. They 
resemble a papular eczema greatly, but their urticarial nature is 
sho^\^l by their evanescence. They are apt to occur over a period of 
several weeks. 

Urticaria with large wheals is not uncommon, large red or white 
wheals being often associated with smaller ones. Sometimes several 
large wheals are closely approximated, forming a large firm swelling 
which resembles confluent insect bites. A minute hemorrhagic point 
in the centre increases the illusion. Large wheals, forming edematous 
tumors, are kno\\Ti as giant urticaria. Urticaria may be complicated 
with purpura (urticaria ha^morrhagica) and there is also a bullous 
type of urticaria (urticaria bullosa). 

Urticaria pigmentosa (Fig. 25), usually regarded as a separate 
affection, may be mentioned here. In this affection the eruption is 
characterized by the usual wheals, but these do not undergo the usual 
involution. Instead they tend to persist indefinitely and a deposit of 
pigment occurs which is virtually permanent. The affection is almost 
peculiar to infants and children. The stains are not due to such 
familiar causes as hemorrhage and scratching, but seem to be part 
of a new formation of tissue, as an integral element in the disease, 
which, while it is but little affected by treatment, is usually outgrown 
at puberty. 

Etiologv 

Urticaria has some deep-seated connection with the vasomotor 
system, and has affinities with the vasomotor neuroses. The first 
step in the formation of a wheal is angiospasm causing an area of 
local anemia. This spasm is followed by sudden vaso-dilatation and 
effusions, which compresses the vessels from without. This causes a 
white wheal with an outlying hyperemic zone. The process resembles 
somewhat the formation of the lesions in erythema multiforme. It 
is evident that the actual cause of the disease is that which tends to 
induce this angiospasm, and this is commonly a circulating toxin 
absorbed from the alimentary canal. Many familiar dietetic articles 
can cause it, the best knowm being shellfish, mushrooms, and straw- 
berries. In many cases there is no evidence to point to any one 
substance, but simply a gastro-enteric crisis due to general dietetic 
abuses. In urticaria of intestinal origin, the intestinal tract may 
suffer as well, as a result of direct irritation from the toxic sub- 

89 



stance. So-called idiosjaicrasy, in which the consumption of a cer- 
tain drug or dietetic article is invariably followed by urticaria, is 
best explained by anaphylaxis — supersensitiveness to the particular 
substance caused by the original unpleasant experience with it. For 
this reason it may be very dangerous for these subjects to make 
use of these substances at all, for the oversensitiveness may so in- 
crease, that the so-called anaphylactic shock may prove fatal, espe- 
cially in individuals with advanced cardiac disease. 

Diagnosis 

Urticaria in 'its simpler form is readily recognizable even by the 
laity, who know it under such names as "hives" and "nettle rash." 
Chronic urticaria, on the contrary, is easily misjudged. It is neces- 
sary to watch for new lesions, and when these are found to be wheals 
the diagnosis is easy. Giant urticaria may readily be taken for some 
local lesion, the result of insect bites, for example; the more so 
because it may be limited to some one area. These cases are usually 
regarded as a transition between urticaria and acute circumscribed 
edema. 

Treatment 

If an acute attack is seen at the outset, a quickly acting purgative 
should be given ; usually one of the salines. Antacids are also given. 
This plan should be pursued whether vomiting and diarrhea are 
present or absent. Any other detoxicating measures available should 
be practised, and this plan of management should be kept up for 
several days. Intestinal antiseptics, colonic irrigation, and simple, 
bland diet are comprised in the management. Some writers advise 
salol in regular doses for its supposed antifermentative properties. 
A combination of alkaline diuretics and bromides appears to aid 
in controlling the disease. Johnston recommends the administration 
of ichthyol in five-grain capsules after meals. This he regards as 
the most serviceable drug for internal medication at our command. 

Locally the antipruritics and sedative measures used in acute dif- 
fuse eczema are indicated. 

Medicated baths frequently allay the cutaneous irritation and 
inflammation. An excellent formula, recommended by Bulkley, is the 
following : 

^ Potassii carbonatis §iv 

Sodii carbonatis 3"i 

Pulveris boracis 3" 

M. Use in a thirty-gallon bath, with a pound or two of starch. 

40 



Owing to the volatile character of the lesions sediment lotions are 
generally inferior to ointments. 

In recurrent and chronic urticaria the management is summed 
up under rigorous intestinal disinfection, including a carefully se- 
lected diet, and some of the same tonic measures as are applied in 
dermatitis herpetiformis.

Dermatitis Medicamentosa 

Plates 18 to 22, Figs. 26 to 33 

This term is employed to denote outbreaks caused by the internal 
administration of drugs, and is not to be confused with the various 
forms of dermatitis venenata caused by the external application of 
remedies. Drug eruptions do not differ essentially from dermatoses 
due to supposed autotoxications and metabolic disorders. In either 
case all the primary and secondary lesions may be represented, and 
marked polymorphism is sometimes seen. These drug rashes may 
also closely simulate the exanthems of acute infectious diseases. Nor 
are lesions due to drugs limited to mere acute efflorescences, for cer- 
tain medicaments can produce chronic, productive and destructive 
lesions like the granulomata. Arsenic can cause an overproduction of 
horny epithelium, sometimes resulting in a malignant growth. 

A very important distinction must be made between customary 
action, supersensitiveness, and idiosyncrasy in respect to this action 
of drugs on the skin. The term idiosyncrasy should not be confound- 
ed with supersensitiveness, for it implies something peculiar to the 
individual and, perhaps, his blood relatives. The idea of supersensi- 
tiveness has received a great impetus in recent years from the study 
of anaphylaxis. Supersensitiveness may, of course, be innate in a 
subject, but it is often the result of a poisoning on some previous occa- 
sion which has rendered the skin supersensitive to the substance in 
question. Anaphylaxis may also result locally, and the sensitiveness 
to poison ivy and the like is doubtless in part anaphylactic. A sub- 
ject supersensitive to one drug may very likely be supersensitive to 
others. No doubt there is a general predisposition to drug eruptions 
based on unusual vasomotor irritability, and hence noted chiefly in 
children, certain women and neurotic subjects. Defective elimination 
has the same significance as overdoses, and certain drug lesions ap- 
pear to have resulted from proved renal insufficiency in elimination. 

A factor of great importance is that the rash, etc., provoked by 
a given medicament is not always connected with its true cause, so 

42 



Plate 18. 




Fig. 26. Dermatitis Medicamentosa (Antipyrine rash). 




Fig. 27. Dermatitis Medicamentosa (Arsenic rasli). 



that the patient continues the use of the drug until a more or less 
serious condition results. 

Few drugs exert tlieir toxic action peculiarly on the skin. It must 
be borne in mind that otlier tissues are usually implicated, and that 
the offending substance leaves the body in the urine, in which it may 
often be detected. 

In some instances a drug which is eliminated by the skin may«come 
in contact with another locally employed. A cTiemical reaction may 
result, causing some local disturbance. The action of light on metal- 
lic salts wliich are in the circulating blood may also cause special 
phenomena, especially of the nature of discoloration of the skin. 

A question naturally arises, are drug rashes to some extent the 
effects of elimination by the skin ? There is little direct evidence as 
to the correctness of this speculation, but beyond the fact that these 
substances are in the circulating blood nothing is really kno^vn as to 
their modus operandi. 

A drug eruption is recognized as such only by the crucial test of 
exhibiting the drug on a second occasion. Its known action on the 
supersensitive usually gives -sufficient information. It is possible, by 
combining certain antagonistic drugs, to prevent many drug erup- 
tions, but there is hardly any special treatment, save in severe chronic 
cases, to be mentioned later. 

Following are some of the leading drugs which cause lesions and 
their symptoms: 

Aniipyrin (Fig. 26) 

This drug does not, as a rule, cause anaphylaxis, but the contrary, 
as many become immune. It causes a general outbreak, but as a rule 
the face and trunk bear the brunt. The rash may be morbilliform, 
searlatinaform or polymorphous. In rare cases bulhc, purpura, and 
pustules have been noted. A feature of especial significance is pig- 
mentation following the eruption. 

Arsenic (Fig. 27) 

This drug is believed to have an elective action on the skin, and 
the number and variety of its collateral phenomena are too great even 
to enumerate. Arsenic can cause a typical herpes zoster, keratosis of 
the palms and soles, gangrene of the scrotum, pigmentation, "and even 
epithelioma. The general pigmentation that frequently follows the 
continued use of arsenic is often mistaken for Addison's disease. 

48 



Bromine (Fig. 29) 

These salts affect nearly all subjects. Bromie acne is much like 
the ordinary form, but has a tendency to confluence, producing a sort 
of small carbuncle. In mild cases lesions are rather confined to the 
face and shoulders, as in acne proper. In bromism supervening sud- 
denly upon large doses the thighs are a favorite locality, and hardly 
any region is immune. In certain cases the papillary layer of the 
skin seems to be stimulated, so that fungoid outgrowths are produced 
without previous ulceration. Cutting off the drug may not be fol- 
lowed at once by improvement. Lesions may even continue to appear. 

Chloral Hydrate 

A typical drug rash not infrequently follows its use. A scarla- 
tinoid exanthem, implicating the mucosa?, and succeeded by desquama- 
tion, is well known. Various anomalous rashes also occur, as in the 
use of other drugs. 

Chlorine (Fig. 32) 

Workers in this gas often suffer from an acne-like affection, be- 
lieved, however, to result from outward exposure, at least in part. 

Copaiba (Fig. 28) 

A peculiar erythematopapular universal efflorescence is often 
seen in gonorrheal subjects who are using the balsam. This rash 
serves greatly to obscure the fact that gonorrhea itself can cause an 
exanthem. 

Iodide of Potassium (Figs. 30-31) 

An acne-like eruption, much like that of bromine salts, is pro- 
duced by this drug, and exceptionally the usual irregular outbreaks 
seen with drugs in general (buUaj, purpura, etc.). There is also a 
peculiar confluent, patchy lesion, somewhat similar to a bromine "car- 
buncle," but more indolent, which seems to be due to a congeries of 
inflamed follicles, and occurs on the legs as a rule. There is also a 
severe, proliferative, and destructive affection, much resembling the 
infectious granulomata, seen on the upper extremities and elsewhere. 
In this form a tendency to buUas exists, and is a leading factor. 

These severe forms of iodism have sometimes been brought in re- 
lation with renal and cardiac insufficiency, but have also been seen 
in apparently vigorous youthful subjects.

Mercury (Fig. 33) 

Erytliematous eruptions sometimes occur after the internal ad- 
ministration of mercury. They may be partial or general. The rash 
is of a deep red color and is often accompanied by swelling and 
pruritus. Occasionally it may be papular or scarlatiniform, and in 
the latter case is generally followed by desquamation. 

Quinia 

Cinchonism is sometimes expressed by eruptions of the same type 
as those due to antipyrin. 

In addition to the preceding, rashes and other manifestations 
have been seen after a great variety of drugs: aconite, acetanilid, 
alcohol (sometimes causes a desquamating erythema), antimony, ben- 
zoic and boric acids, calx sulphurata, cannabis Indica, chloroform, 
cubebs, digitalis, ergot (not including severe ergotism), opium (pru- 
ritus a very conmion sequence), phenacetin, rhubarb, salicylic acid 
and derivatives, sulphonal, turpentine, and numerous others.

Lichen Simplex Chronicus Vidal 

Synonym : Neurodermatitis 

Plate 23, Fig. 34 

This affection, unlike true lichen, is an extremely chronic one. It 
attacks by preference the neck, the inner surface of the upper parts 
of the thighs, and the flexor folds of the knees and elbows. Excep- 
tionally the abdomen may be affected. The lesions are papules of the 
simple lichen type, equivalent to those often seen in eczema. They 
are naturally discrete but readily become confluent. Well marked 
cases show a central area of lichenification of a grayish-brown color, 
which is surrounded by a brighter zone in which are present small, 
slightly scaly lichenoid papules. Vidal claimed that the disease is 
essentially a pruritus and that the cutaneous manifestations are due 
entirely to the results of scratching — hence an artefact, or form of 
dermatitis, confined largely to the pilous follicles. The deep red, 
angry look of the papules, if not the lesions themselves, he ascribed 
to rubbing and scratching. 

Etiology 

The disease affects only neurotic individuals and is more frequent 
in women than in men. 

Diagnosis 

This should not be difficult in a fully developed case. It is dis- 
tinguished from other similar conditions by the duration, localization, 
and absence of marked inflammatory phenomena. 

Prognosis 

The condition is chronic in the sense that new outbreaks constantly 
occur. 

Treatment 

General measures directed to the relief of the pruritus are, of 
course, indicated. The local treatment is essentially that of chronic 
eczema. In severe cases chrysarobin ointment is often of considerable 
benefit. Solutions of oil of cade are also useful.

Pityriasis Rubra Pilaris 

Plate 23, Fio. 35 

This affection appears to be a dermatitis involving the hair-fol- 
licles. It is extremely persistent and has no particular secondary 
tendencies. Unlike types of folliculitis, it may involve the entire sys- 
tem of hair-follicles of the smooth as well as the hairy skin, producing 
large sheets of inflamed integument and becoming practically univer- 
sal in certain cases. The separate papules, however, can always be 
distinguished. Considerable fine desquamation is present, hence the 
use of the term pityriasis. General scaling, however, does not occur. 

An incipient case naturally presents a different picture from one 
well advanced, for, as a rule, the disease begins in a limited area, 
and sometimes remains there. Such areas are the scalp, and the 
palms and soles. In the latter localities there may be only callous 
thickenings, while in the scalp ordinary or seborrheic eczema may be 
simulated. Lesions then appear in various other localities — as the 
fingers, forearms, trunk, etc., where their development may be readily 
studied. The papules may be red or they may have a brownish or 
grayish color. Each follicle may be the seat of a smaU hard central 
plug as well as a hair-stump. As they become confluent the corium 
shows participation. It becomes thicker and less supple, and may 
crack slightly at the natural folds. "Wlien the entire face is involved 
there may be some retraction about the orifices. Alopecia does not 
result, but the nails may become brittle. It is one of the few der- 
matoses able to implicate practically the entire integument. The 
thickening of the skin gives the latter a coarsely granular appearance. 

Etiology 

The affection is rare, and its nosologic position has been much de- 
bated. It was once believed to be the same disease as lichen ruber 
acuminatus. A stumbling-block was the high mortality of the latter 
as described. But at Vienna, where fatal liclien ruber was first noted, 
no fatalities or even cases of marked severity are now recorded, nor 
has any fatal type been seen for years. For a time it was believed 

47 



that lives were saved only by the heroic use of arsenic, but this was 
doubtless a misapprehension, and it is not improbable that some of 
the recorded deaths resulted from the misuse of .this drug. Arsenic 
now seems to have little or no power over the disease. 

Nothing whatever is known as to its causal elements. It may be- 
gin in childhood, and is an affection of early life. It shows no 
familial incidence, and occurs in the sound and vigorous. As a hy- 
perkeratosis, which it appears to be, with inflammatory phenomena 
purely secondary, it shows an affinity with psoriasis. The reaction of 
the corium to the epidermal process is similar. The very participa- 
tion of the entire follicular system seems to coimect it with some fun- 
damental error of development. 

Diagnosis 

At the very outset lichen rubra pilaris might be suggested, or ordi- 
nary dandruff and callosities. As the disease develops there shoidd 
be no further trouble in identifying it until it becomes universal. The 
papules are usually seen in a typical state on the backs of the fingers. 
Since the affection has been made a congener of lichen planus, it is 
evident that the two could be confused, especially as in lichen planus 
the papules are not invariably flattened. The initial lesions, however, 
are so typical in each affection that confusion should hardly occur. 
When the eruption becomes universal, psoriasis and eczema may be 
simulated, but the elementary lesions, and especially the evolution of 
the disease, should prevent confusion. 

Prognosis 

Arrest, spontaneous cure, cure by treatment, all occur. Recur- 
rence also occurs, and in many cases the tendency is progressive from 
first to last. The general health is but seldom affected. 

Treatment 

Of treatment in the ordinary sense, with a view of a cure, there is 
none. The management comprises, in a general way, that of eczema, 
psoriasis, and ichthyosis. Alkaline baths, subsequent inunctions, and 
salicylic acid ointment tend to remove the overproduction of corneous 
matter and hence to check the inflammation. This must be persisted 
in, and thus conditions are made favorable for improvement and 
recovery.

Eczema 

Plates 24 to 29, Figs. 36 to 46 

The conception of eczema has constantly undergone changes, some 
of them radical, since the terra was lirst introduced by the Greeks. 
The "boiling over," which the word signifies, does not refer to the 
discharge of moist eczema, but to hot, burning pustules appearing 
over the entire surface — in other words, furunculosis. Eczema meant 
nothing else until the time of Willan, who applied the term to cer- 
tain forms of dermatitis due to known irritants, characterized by 
minute vesicles or vesicopustules, closely aggregated and diffused 
over the irritated area. Thus far there was no suggestion of any- 
thing but an acute affection. Biett, and especially Bayer, isolated 
vesicular eczema from the artificial eruptions, and incidentally estab- 
lished the fact that the former could represent a chronic condition ; 
that it was not rare but extremely common, and that itching was 
characteristic — an itching vesicular eruption, running chiefly a 
chronic course. Bayer also regarded the affection of the face and 
scalp, previously known as milk crust, as an acute phase of eczema. 
After an interval of great confusion, Devergie made another advance 
by retiring the vesicle as a characteristic lesion. The most essential 
phenomena for him were redness, a discharge which stains and 
stiffens linen, and violent itching. Hehra was the first to insist that 
eczema may never reach the weeping stage, and may exhibit only 
diffuse redness and desquamation or dry papulation. He isolated 
five clinical types — squamous, papular, vesicular, the red weeping 
type (eczema rubrum or madidans), and impetigenous eczema. This 
conception of eczema has not been radically changed since, but it be- 
came apparent in time that there were primary forms — erythematous, 
papular, vesicular, and pustular — and secondary forms — eczema 
rubrum and eczema squamosum. The condition known as eczema 
seborrhoicum, added by Unna to the basic forms of the disease, is 
considered elsewhere. 

Eczema is a superficial inflammation of the skin, and the claim is 
made that all its manifestations may bo produced experimentally, by 

49 



local irritation; while it may exceptionally pursue an acute course, 
or occur in mild and abortive forms, it is essentially a chronic affec- 
tion; while it may remain localized in the area originally involved, 
its natural tendency is to spread ; the one most characteristic feature 
is violent itching, with m ore or less .burning ; it is non-contagious ; it 
never induces scarring ; it exhibits primary and secondary phases, or, 
as some would call them, initial and mature phases. It occurs in any 
area of the integument, and its manifestations vary greatly with the 
locality involved and the degree and extent of the process. Different 
lesions may occur in the same subject, and everything makes_for 
polymorphism. 

Once looked upon as a rare affection, eczema is now by far the 
most frequent of all dermatoses. Wliether the present conception of 
it will stand is uncertain. The term "the eczemas," representing a 
great group disease, would in some ways be preferable to "eczema." 
It could then include dermatitis and possibly other affections. 

Etiology 

Eczema is produced preeminently by a coincidence of predispos- 
ing and exciting factors. If it could be explained by the action of the 
latter "wdthout the element of predisposition, we should then rank it 
as a dermatitis or perhaps a parasitic disease. If there is no evi- 
dence of any external irritant we may assume the existence of some 
ultramicroscopic germ, or that some acute metabolic or other auto- 
toxic disorder acts as an exciting cause. Both exciting and predis- 
posing factors may escape us; but in very many cases the etiology 
is evident enough. These form a connecting link between eczema and 
dermatitis. Here we see a single exciting cause able to set up, in 
the absence of any marked predisposition, a condition which behaves 
clinically as an eczema. With the removal of the exciting cause, 
there shoiild be a tendency to recover permanently, although the con- 
dition would perhaps require further treatment. When the evidence 
of a predisposition is apparent, despite the presence of an original 
exciting cause, as shown by a tendency to spread or to relapse spon- 
taneously, we are forced to assume the existence of a diathesis. In 
earlier times it was customary, at least in France, to accuse various 
diatheses, and it is interesting to note that the idea of diathesis in 
this connection has recently been revived in Germany, where it was 
originally reviled. If we assume with Unna and others that a bacte- 
rial factor must invariably bo present, then the term diathesis would 
simply mean the sum of all the conditions which tend to make the skin 
a good culture medium. It is the relative preponderance of predis- 

50 



posing overexciting causes, or the converse, which makes nearly every 
case of eczema a law to itself, and which tends to the formation of a 
great number of clinical types, which may differ as much among 
themselves as if they were quite distinct diseases. 

In England, where gout is prevalent, * 'gouty" eczema appears to 
be common and easily recognized. To call an eczema gouty, how- 
ever, does not mean, as Unna implies, that it must be set up by the 
irritation of uric acid crystals. A predisposition and an excitation 
may both come about from defective metabolism. This is seen dis- 
tinctly in the genital eczema of diabetics, in which the irritating urine 
promptly sets up vulval eczema, which is invited by the abnormal 
metabolism of the patient. 

All the kno^\^l metabolic affections favor the development of 
eczema; and while these may occur at any age, they are practically 
inevitable in advanced years, and are very largely sufficient in them- 
selves to explain eczema at that period of life, which may, of course, 
come about prematurely. 

Equally striking is the relationship between the diet and diges- 
tive organs and the peculiar types of eczema in the nursling, which 
affect chiefly the face and scalp with a moist, crusting process. It 
has long been noted that babies with this type of eczema, although 
they may feed heartily, do not vomit or regurgitate. Countless cases 
of eczema in infants can be traced to the custom of drinking beer 
freely by their nursing mothers, and they generally recover as soon 
as the mother's diet is supervised. So slight a correction of the diet 
of a bottle-fed baby as lengthening the interval between feedings has 
frequently been followed by very decided improvement even in severe 
cases. 

In certain local types of eczema, the dependence on a single clean- 
cut cause, whether we term this predisposing or exciting, is marked 
— so much so that we hesitate about calling it eczema. Here belong 
the various eczemas of the legs and scrotum, the orificial eczemas due 
to irritating secretions, especially those of the upper lip, nipples, and 
genitals, the intertriginous eczemas, etc. Like the professional ecze- 
mas so-callod, all these appear to form a link between dermatitis and 
the purest forms of eczema. 

Another point of contact between eczema and dermatitis of me- 
chanical cause is very often conspicuous. In certain types of eczema 
tlie itching is by far the most prominent sjTiiptom. The actual lesions 
are barely evident as minute papules or even a mere redness, repre- 
senting abortive forms. As a result of the itching, the great major- 

61 



ity of the lesions are artefacts, produced by scratching, rubbing, etc. 
The extensive hypertrophic thickening of the skin in some cases of 
clironic eczema may be due very largely to habitual irritation. So 
notable is the tendency to scratch in eczema that it is often difficult 
to get an idea of the actual lesions of the disease. Many are of the 
opinion that if scratching could be prevented at the outset eczema 
would be a disease of trifling lesions only. 

Many cases of eczema occur under such circumstances of loca- 
tion and form, that, in the total absence of predisposing or exciting 
factors, we can think only of a parasitic origin. Here belongs espe- 
cially the nummular eczema on the backs of the hands, fingers, fore- 
arms, etc. The parasitic origin is even more plausible in so-called 
seborrheic eczema, which is seen especially on the scalp, face, ster- 
num, intrascapular region, etc., and which exceptionally occurs any- 
where on the surface. The appearance and mode of spreading of all 
these lesions suggests a parasitic cause. 

An eczema varies considerably in its lesions according to locality. 
On hairy regions it is much more inclined to form pus than on smooth 
ones, because infection with pyogenic germs comes about with greater 
certainty. In folds eczema has a greater tendency to become moist 
than elsewhere, although the worst tj'pes of weeping eczema occur 
quite independently of location. Eczema of the palms and soles is 
naturally attended by much more thickening of the epidermal layers 
than in other localities. "When eczema occurs in the rosacea area 
of the face it is often difficult to distinguish it from the latter affec- 
tion. 

Acute erythematous eczema of the face may cause an unusual 
amount of swelling, the eyelids becoming so edematous that they can- 
not be opened. 

Diagnosis 

Enough has already been said of the characteristic features of 
eczema, and it only remains to give the differential diagnosis. To 
discriminate between acute eczema of the face and erysipelas is a 
matter of vital importance, for it no doubt happens at times that 
patients with the former are isolated and treated as very sick individ- 
uals. The patient mth eczema is never affected constitutionally, 
although very young children may present some malaise and tem- 
perature. He has no toxemia, no fever or prostration. His face may 
resemble greatly the erysipelas mask, but the swelling is not brawny 
nor is the contour sharp and indented. In eczema the color shades 
gradually into the normal tint. 

52 



Dry squamous eczema may greatly resemble psoriasis, but the 
proper diagnosis should be made in any doubtful case after a proper 
amoimt of observation. 

WTiat is true of psoriasis applies to some extent to lichen planus. 
When the patches first appear they may closely resemble eczema. 
Study of the case will probably lead sooner or later to tlie recognition 
of the peculiar primary lesion of lichen, the triangular dellated 
papule ; .just as in psoriasis, the minute papule with its disproportion- 
ately thick crust will reveal that affection. Pustular eczema is readily 
confounded with other pustular eruptions, but as far as the secondary 
pyogenic infection is concerned it is practically the same condition 
throi;ghout, demanding much the same management. 

Two such multiform affectidiis as syphili s and ecz ema nmst at 
w times Simula 1 1' farli oilier. Squamous eczema sometimes bears con- 
^^'^ siderable reseniblanee to i)apulosquamous syphilides, and palmar and

affection, the presence or abs ence of itchin g (the only sypliilidc which 
itches at time? is the generaEzed ga^ular eruption, a coiniiaratively 

VlaT e secondary phenome non) ,~a"n3r finally tlie elTc .t ot anti-sypliilitic 
treatment. The prefungoid eruption in granuloma fungoides is often 
indistinguishable from a chronic eczema. 






Treatment 

If there is any evidence of faulty metabolism or any derangement 
of the digestive apparatus, or if the diet of the patient is badly chosen, 
he will not be likely to recover unless these conditions are first cor- 
rected. It is a common experience that not only eczema but nimierous 
other dermatoses, such as all forms of seborrhea and acne, pruritus, 
chronic urticaria, etc., tend to improve, and become aggravated under 
much the same conditions of general nutrition, digestion and diet. 
The same individual may present a number of these affections at the 
same time or in succession. Placed upon a restricted diet and general 
hygienic regimen of exercise, hydrotherapy, etc., all these conditions 
show a common tendency to improve. Some connection is often 
apparent between these dermatoses and overweight. As the subject's 
weight is reduced by his regimen the resistance of the skin increases. 
This general therapeutic indication must always be borne in mind in 
the management of eczema. The predisposition herein implied is not 
deep-seated enough to be termed an inborn diatliesis, but simply the 
result of malhygiene and hence preventable. Even the deep-seated 

68 



■^ 



metabolic anomalies of actual or premature senility are not neces- 
sarily diathetic but are due chiefly to the fact that with advancing 
years the subject continues to eat heartily while exercising progres- 
sively less. The nutrition in all these subjects has become so de- 
ranged that the skin may become a culture medium for ordinary 
pathogenic cocci and even for others which ordinarily are harmless 
saprophytes. 

The limits of this article do not afford scope for a consideration of 
the general management of eczema, but under etiology the various 
causal factors were considered. In regard to the subject of inter- 
nal medication in eczema, certain remedies are no doubt highly bene- 
ficial, although the rationale may not be clear. In any case of acute 
generalized eczema or acute eczema of the face large doses of acetate 
of potassium have been used with success for over a century. 

The belief formerly prevailed that acute eczema of internal causa- 
tion was dependent in some way on acute renal insufficiency, the urine 
being commonly concentrated. The diuretic action of the potash ap- 
peared to be succeeded by a rapid retrogression of the eruption. It 
has been pointed out that in renal disease we naturally stimulate the 
skin, and that the opposite course is rational when conditions are 
reversed. The extreme swelling of the eyelids in acute eczema 
of the face certainly appears to yield promptly to the action of 
diuretics. 

The action of arsenic on chronic eczema is unmistak able an d_it is 
often use^ hypbdeVhlicallylo secure prompt results. 

Internal remedies — sedatives and hypnotics — have some influence 
over the itching, enough to aid the patient in getting his sleep. Gel- 
semium has been recommended in desperate cases. More recently the 
various synthetic analgesics — phenacetin, antipyrin, etc. — have been 
used for this purpose. 

Locally, the principal indication is to subdue the itching, for in 
many cases this represents almost the whole of the disease, the lesions 
being principally those arising from constant scratching and rubbing. 
It is never advisable to dissuade the patient from scratching, as this 
is often beyond his power. No one substance has any constant superi- 
ority as an antipriiritic. Phenol, menthol, chloral, camphor, corrosive 
sublimate are some of the more powerful remedies used, but milder 
substances, like boric and salicylic acid and thymol, may be sub- 
stituted. 

In acute eczema the antipruritic may be combined with anti- 
phlogistic remedies when these are indicated. The ointment or the 



sodimont in tlio lotions also serves the purpose of excluding the 
air, which intensifies the itching. The substances used to form the 
sediment are usually zinc or bismuth compounds, which have an anti- 
phlogistic action, and are also added to the ointments. A good oint- 
ment may be made wth cold cream as a base and should contain 
calamine, zinc oxide or bismuth subnitrate with the addition of phe- 
nol, menthol or camphor. A corresponding lotion should have as a 
vehicle weak lime water, and contain the same ingredients. Oint- 
ments give the best results when they can be applied with a fixed 
dressing, but lotions are preferred for all exposed localities for their 
cosmetic possibilities. Whenever the inflammatory reaction is con- 
siderable, ichthyol is indicated, and in some cases may be combined 
with the remedies already mentioned. 

Most acute cases should recover promptly if the dressiogs could 
be made permanent and changed only once a day. In practice, how- 
ever, this is seldom practicable, as patients do not wish to be inval- 
ided. Hence a compromise treatment must be devised. The patient 
must forego washing his skin or disturbing it in any way, excepting 
with a special technique. Since ointments cannot be used freely in 
ambulatory cases during the day, it is the custom to use lotions at that 
period and ointments at night. This necessitates removing the oint- 
ment in the morning, which is done preferably with suds of tar 
soap. The skin is then dried by simply blotting it with gauze and 
the lotion applied thickly. If the locality is such that the sediment 
wears away it must be repeated over and over. The parts are thus 
kept constantly protected from the air and in contact w'ith antipruritic 
and sedative substances. 

If a large area of integument is involved, the patient should take 
a medicated bath on retiring, A pound each of starch and soda may 
be placed in the bathtub and allowed to dry upon the skin of the pa- 
tient. If the surface involved is large, ointments and lotions cannot 
be applied thickly. A thin layer of carbolized vaseline will answer, 
for the skin has already received a coating of soda and starch. 

Dusting powders are also serviceable when there is a large area of 
skin involved, and they may also be applied over the lotions. They 
may be applied in all exudative cases, but possess no advantage over 
sediment lotions made with the same substances save for the extreme 
facility with which they may be applied. They are useful in hospital 
and dispensary practice. 

^Vhile ointments cannot well be used over weeping surfaces in the 
ordinary state, they may be combined with starch, casein, zinc oxide, 

65 



etc., in special percentages — generally equal parts of vaseline and 
powder. If these pastes so-called are applied firmly with fixed dress- 
ings, the fluid is absorbed.

Prurigo 

Plate 30, Figs. 47 and 48 

This affection is comparatively rare in the United States and the 
cases encountered are generally observed in iimnigrants from Central 
I'^urope. All attempts to connect it nostologically with papular and 
itching affections seen in this country are futile. Wliile it may occur 
sporadically in the very poor and desolate in any country, this fact in 
no wise accounts for its cumulation in Austria-Hungary. 

While prurigo may begin with the simple itching of an intact skin, 
or one with urticaria papulosa, the most intense and persistent 
scratching in other dermatoses does not commonly transform them 
into true prurigo. Even the so-called mild form of the latter retains 
its indi%aduality and is not chronic urticaria. 

Prurigo no doubt begins as wheals, especially in nurslings, and 
to a progressively less extent as the age increases. Cases are now 
alleged to begin in adults. Adhering chiefly to the original descrip- 
tion of the Vienna dermatologists, it persists until the early part of 
the second year as a mere association of urticarial papules and 
wheals and scratch marks. These are at once supplanted by papules 
which are of the color of normal integument and represent inflanmia- 
tory formations. The latter no doubt represent old urticarial pap- 
ules. In the meantime itching reaches a maximum, so that sleeping 
becomes difficult. A scratch dermatitis develops, but not in excess 
of what may be seen in other pruriginous dermatoses. The prurigo 
papules are not of this origin, although doubtless intensified thereby. 

The disease may reach an acme of severity before the third year 
is passed. The papules occupy chiefly the exterior surfaces of the 
extremities, especially the lower. The ocular appearance is some- 
times deceptive, so that the sense of touch is indispensable for diag- 
nosis. The lesions project slightly above the skin level, so that a 
papule very often exhibits a dot of dried blood on its summit from 
scratching. Trophic disturbances seem in evidence, as the skin is 
unnaturally dry and rough, the hair dry, etc. Further changes due 

67 



to protracted scratching are thickening of the skin, pigmentation, and 
at times areas of simple dermatitis not comiected with the disease. 
One of the most characteristic symptoms is the chronic inguinal bubo 
commonly present in fully developed cases. Patients with chronic 
prurigo generally show failure of nutrition. 

Etiology 

Age has already been mentioned. Prurigo is never inlierited, 
never congenital. Some familial predisposition is seen at times. 
There seems no doubt that it develops on an urticarial basis. As a 
rule urticaria of childliood has no sequelae, and even the worst cases 
of prurigo are sometimes outgrown at an early period. The unknown 
X is involved in the problem of the transition of an urticaria into 
prurigo. The evidence of a dystrophic skin as the cause is not suffi- 
cient, and at present we have no clue to this factor. 

Diagnosis 

This is made first by the location and history of early develop- 
ment ; the characteristic papules and inguinal buboes ; the dry skin ; 
and further by exclusion of eczema (especially in a dry skin) ; para- 
sitic diseases and other forms of itching affections. 

Prognosis 

This should be guarded as to the duration of the disease. 

Treatment 

Hygienic and nutritive management represents the first line of 
treatment. A course of quiet with liberal feeding is rationally 
indicated. Pilocarpin antagonizes the dry skin. The itching and 
irritation require warm alkaline baths, followed by inunctions with 
ointments containing phenol, naphthol, tar, etc.

Figs. 52 and 53 

This is a unique affection, the characteristic lesion of which is a 
small papule, flat and triangular or polyhedral, having a minute 
central depression ; the color is deep red or livid and a peculiar waxy 
lustre is evident. These papules, naturally isolated, readily coalesce 
to form patches and sometimes rings. In a patch it is usually possi- 
ble to recognize the original papules, whose borders and depressions 
still persist. The patches show a slight degree of sealing. As a rule 
the papules are extremely persistent and are liable to come out in 
successive crops. There is some tendency to pale out and undergo a 
sort of atrophy. The typical papule is less than an eighth of an inch 
in diameter. In some subjects they leave deep pigmentation. 

The disease is naturally disposed to a general distribution but has 
certain areas of preference as the flexor surface of the forearms and 
lower portion of the legs. The papules are sparsely distributed at 
first and later become more dense, but do not tend to appear at the 
outset in isolated groups. Exceptions occur, however. As already 
stated small rings of papules sometimes form or the latter may be 
arranged in chains. When the disease attacks the glans and foreskin 
or the inside of the cheeks, the papules appear closelj' grouped and 
in fact may be confined to one or both of these situations. Exception- 
ally they are seen on the female genitals, and the tongue. On all 
these mucous surfaces the papules have a whitish appearance, save 
in persons with exposed glans where the eruption resembles that on 
the skin. 

Lichen often assumes a chronic form and presents a notable degree 
of itching, so that the effects of prolonged scratching are sometimes 
apparent. 

Etiology 

The causation of lichen planus is still a matter of conjecture. It 
is generally regarded as being dependent on some form of nerve dis- 
order, and in patients presenting acute general eruptions, with intense 
pruritus, it is seldom difficult to obtain evidence tending to support 
this theory. They are often either apprehensive or depressed, and 
the history of recent shock or fright is occasionally obtained. LUce 

59 



many another affection, lichen planus often develops in subjects 
whose resistance has been diminished by poor nutrition, overwork 
and nervous insufficiency, but there seems to be no warrant for mak- 
ing it a neurosis. It may occur in young and apparently vigorous 
subjects. Some authorities now regard the disease as an infective 
granuloma. The lesions appear to represent an inflammatory infiltra- 
tion in the outer portion of the corium, involving some thickening of 
the rete and horny layer, and hypertrophy of the papillae. 

Diagnosis 

Wliile numerous other affections produce papules none of these 
resembles in the slightest the lesion of lichen planus. Once seen, the 
latter could hardly be forgotten. Wlien, however, the lesions become 
grouped, the patches readily simulate chronic squamous affections. 
This is especially prone to occiar when large patches are formed in 
some unusual locality, as over the knees. Lichen may also show a 
special tendency to form multiple scaling patches. When rings are 
formed showing various stages of development it may be necessary 
to exclude the other ringed affections, as syphilis, ringworm, etc. 
Confusion with lichen ruber of Hehra is doubtless due to the fact that 
atypical forms of each may simulate the other. Typical cases show 
no parallelism. 

Prognosis 

The affection is naturally chronic and sometimes progressive. In 
many cases, however, there seems to be a natural tendency to recov- 
ery. With proper treatment the outlook for recovery is always good. 

Treatment 

This is influenced largely by the stage of the disease and the type 
of eruption presented. In the acute hyperemic, disseminated variety 
the internal treatment should at first consist only of alkaline mix- 
tures. The following are good examples :

Mild laxativos are also indicated, the diet should be restricted and 
alcoliol prohibited. The discontinuance of tobacco is not always 
advisable, as it often seems to increase the nervous irritability. As 
soon as the acute stage begins to subside, mercurial treatment should 
be instituted, for there is now but little doubt as to the superiority of 
mercury over all other drugs in the treatment of this disease. In 
many cases its effect is almost specific. The results, however, are not 
always uniform. It should be administered in increasing doses until 
either improvement in the eruption occurs, or beginning mercurial- 
ism is noticed. A fairly accurate method of administration is in the 
form of one-grain tablets of hydrargynmi cum creta. From six to 
twelve of these may be taken daily, according to the effect produced. 
Mercury can also be advantageously given in the form of bichloride, 
Hz to H2 of a grain three times a day. This is best given in a 
mixture, but in certain selected cases it may be administered 
intravenously. 

Should the treatment with mercury be unsatisfactory, recourse 
may be had to arsenic, which must also be given in full doses, but 
never in the acute stage. It can be administered in the form of 
Fowler's or Pearson's solutions, in doses of from five to twelve 
minims three times per day. A more convenient method of adminis- 
tering arsenic is in the form of tablets or pills. A tablet containing 
^^0 of a grain of sodium arseniate may be taken after each meal, and 
the dose increased by one every three days until three are taken after 
each meal, then return is made to the first dosage. Occasionally the 
Asiatic pill, which contains Ho of a grain of arsenious acid, is useful. 
Intramuscular injections of cacodylate of sodium have been recom- 
mended, and recently there have been a few favorable reports from 
the use of salvarsan intravenously administered. 

In acute cases, where arsenic is contraindicated, Pringle recom- 
mends the wine of antimony in fifteen-minim doses, three times a day. 
The same writer has reported rapid subsidence of inflammation and 
complete cessation of itching in an acute case after the use of antipy- 
rin in ten-grain doses given three times a day. Bulkley uses chlorate 
of potassa, five to ten grains in water, after meals, followed half an 
hour later by two to five drops of strong nitric acid, well diluted. 
Eartzell has had favorable results from the salicylate of soda. Con- 
stitutional treatment should be continued for some time after the 
eruption has disappeared. The nervous exhaustion that not infre- 
quently follows a severe attack of lichen planus is best overcome by 
the use of strychnine. Tablets of strychnia nitrate of Ho of a grain 
may be given three times a day. The glycerophosphates of lime and 

61 



soda are also useful, and the following formula, in which they are 
combined with strychnia, is an excellent one:

in the main of cooling lotions, such as the calamine and zinc lotion, or :

Alkaline and bran baths are cooling and generally grateful. 

As soon as the acute symptoms subside, mildly antiseptic oint- 
ments, such as ammoniated mercury 2i^% or salicylic acid 5%, can 
be used. Tar, in the form of lotion, ointment or paste, is useful. In 
the chronic type the following ointment, recommended by Unna, may 
be applied :

This affection, because of its characteristic, scaly, white spots, and 
its intractable character, is believed to have been comprised in the 
original conception of leprosy, and perhaps to have made up much of 
biblical leprosy. The superstitions which have come down to us at- 
tached to the scaliness of leprosy and the contagious nature of the 
scabs are hardly reconcilable with what we know of leprosy to-day. 
On the other hand, the affection known to the Greeks as "alphos" ap- 
plies in a measure to vitiligo, a white but not a scaly dermatosis. The 
very word lepra implies a scale, and it must be remembered that the 
Greek word for true leprosy was elephantiasis. Psoriasis may there- 
fore have been the lepra of the Greeks, but this was not true leprosy. 
The dissimilarity between these affections is very marked, and the 
confusion is due entirely to ancient etymological misconceptions. 

Psoriasis in its inception is a sharply individualized disease. The 
first lesion to appear is a small red papule the size of a pin-head or 
point. This is surmounted by a fine silvery scale. "Wlien tliis minute 
scale is picked off a hyperemic base is disclosed. This has been aptly 
termed the pathological unit, for from it all the other lesions of the 
disease are derived. There is no other dermatosis whicli, beginning 
as a mere point in the skin, presents at the same time a definite scale. 
After a large area of psoriasis has once been formed the scaling is not 
so much in evidence. We see a congested and slightly infiltrated area, 
surmounted by scales, but not differentiated sharply from other red, 
squamous affections. The spots with which psoriasis begins vary 
much in size and in thickness of scale with the individual case ; but 
generally speaking, the size of the scale is out of all proportion to the 
degree of subjacent disturbance. A thick, adherent crustlike scale 
may be seated on an area of skin but slightly compromised. Histo- 
logically, as might be expected, psoriasis proves to be an affection of 

68 



the epidermis. Tlie papillary layer of the corium is only secondarily 
involved, from a tendency of the rete to grow inward. 

Psoriasis is eminently a general dermatosis, despite the fact that 
it may sometimes be located for the time in narrow areas. As a rule 
it appears widespread, and lesions may occur in any locality. As an 
eminently disseminated affection, it may appear simultaneously in a 
number of localities, although most prominently in some one area. 
There may be a thick crop over the small of the back and buttocks 
with more sparse lesions elsewhere. Much depends upon the course. 
The more acute the outbreak the greater may be the range of localities 
involved. The more chronic, conversely, the more the affection may 
favor certain localities — for example, the scalp, elbows and knees. 

In an outbreak of psoriasis, as with other dermatoses, two ele- 
ments enter. First, the localities originally attacked ; and second, the 
course of the affection in these original localities. Suppose the latter 
to be any one of the favorite seats of the disease. There may be no 
spread of the affection from the primary focus ; in fact, after a sta- 
tionary period, there may be spontaneous involution. This, however, 
is exceptional. All large, figurate lesions in psoriasis, wherever or 
however produced, come about from changes in elementary lesions. 
Psoriasis is a disease naturally macular or maculopapular in char- 
acter. The mere surface points or droplets with which the affection 
begins may increase to the size of a large coin, but seldom beyond this. 
"Whenever this or any considerable size is reached, the patch tends to 
clear up in the centre, leaving a ring ; while the fusion of annular seg- 
ments produces a gyrate pattern. The original nummular patches 
may fuse together, with the production of wide, diffuse areas. Psor- 
iasis, then, begins as a point and may increase to the size of a pea or 
to that of any of the coins. At any stage its growth may become 
arrested. The individual lesions may be thickly grouped, and fusion 
may occur at any stage. But at any time one of the larger lesions 
may clear up in its centre, leaving a ring ; and coalescence of these 
partially involved lesions may give rise to peculiar figurate patterns. 

The more rapid the evolution of a psoriasis, the greater the dis- 
semination and the less in evidence the scaling. Such cases suggest 
a rash, and may even burn and itch. In some cases it seems hardly 
conceivable that such eruptions are really psoriasis. It is of course 
possible that some ordinary rash can incite the appearance of a 
psoriasis in one disposed to it. That local conditions shape the dis- 
tribution is well shoA\Ti by the occasional appearance of the disease in 
recent cuts, scratches and burns. 

64 



In the consideration of psoriasis, we must know how the affection 
originates ; for once it is in full evolution it can hardly be reduced to 
sjnnptomatology. Aside from a few localities, like the elbows, knees 
and scalp, psoriasis presents no particular local types. It affects the 
extensor more than the flexor surfaces, and usually spares the palms 
and soles, save in the generalized cases. The face, especially the more 
central portion, is seldom attacked. In certain cases it may affect the 
entire integument, causing general exfoliative dermatitis. It seldom 
influences the texture of the skin, so that pigmentation and cicatriza- 
tion do not occur. 

Etiology 

"We know but little about the nature of psoriasis; attempts to 
connect it with causal elements produce different results in different 
countries. There is no doubt that the disease is aggravated by what- 
ever influences that make for rheumatism and arthritism so-called, 
such as cold weather, inactivity, overeating, etc., but this influence can 
only be an indirect one. Its occurrence in members of the same 
families has never been worked out satisfactorily. We do not know 
positively that the disease is truly a familial one, for it is possible 
that it is mildly contagious. All attempts to discover and isolate a 
parasite have failed, yet the course of the lesions sometimes resemble 
strongly that of known parasitic diseases. 

A neuropathic element, often markedly in evidence, is probably 
only a predisposing factor. As already stated, the affection is pri- 
marily one of the epidermis — the rete. The participation of the 
blood-vessels and the papillary layer of the corium appears to be 
secondary. 

Diagnosis 

The initial lesions, already described, are unmistakable; and a 
highly developed case, with its universal distribution affecting most 
markedly the extensor surfaces with its peculiar scaliness and con- 
figuration, is likewise unmistakable. Confusion is most likely to occur 
in isolated patches, say those on the scalp, about the ears, on the 
elbows and knees, etc., for eczema may attack the same localities and 
present much the same appearance. Exceptionally localized psoriasis 
has been seen in eczema areas, and differentiation is so difficult that 
hybrid types are spoken of. Whenever scaly, dry eczema, or sebor- 
rhoic dermatitis appears to be especially resistant to treatment, and 
to return promptly and without manifest cause, it is well to study the 

66 



case closely for evidences of psoriasis. In these cases the characteris- 
tic initial lesions may be detected. 

A treated psoriasis is often impossible of recognition at first. The 
previous treatment may have removed the scales, so that we see only 
hyperemic macules, and rings. The condition may be readily mis- 
taken for a papular syphilide. It is often well to leave such cases 
without local treatment for a few days, when the peculiar crustlike 
scales will form. In some cases, however, scaling is naturally slight 
and here, of course, diagnosis may be difficult. Psoriasis may develop 
in a subject with syphilis. Hence the Wassermann reaction may be 
misleading. 

Prognosis 

Psoriasis is one of the most inveterate of all affections, but it 
responds to treatment to a notable extent, and months, often years, 
may elapse between outbreaks. The affection is not progressive with 
years, and leads to no serious consequences of any sort. Much de- 
pends on the appearance of new lesions, for in some subjects these 
appear almost continually, and little or nothing can be done to arrest 
them, unless the process is relatively slow and local, when if put on 
a thorough regimen it may be possible to check the outbreak. Much 
also depends on the tendency of lesions to enlarge and form patches 
of size, for in many cases the spots do not pass beyond the guttate 
stage. It is the combination of these two factors which causes the 
most severe cases. The more vigorously the disease is combated 
the better should be the prognosis; but there are exceptions, for 
too vigorous treatment sometimes seems to inmiunize the skin to 
the favorable action of the remedies, and it is also possible for a case 
to advance steadily despite the most careful treatment. 

Treatment 

On a carefully selected diet and regimen, such as benefit eczema 
and acne, psoriasis also improves. Lesions clear up when training 
for athletic events and also upon low plans of diet. This kind of man- 
agement naturally renders the skin a more unfavorable culture me- 
dium for germs of all kinds, but does not justify the claim that 
psoriasis is due to a germ. No matter what the state of the individual, 
attempts should be made to render all his functions normal, whether 
he is to be built up or reduced. Going bare in the outdoor air and 
sunlight is believed by Piffard to have a natural curative tendency. 

66 



K any well-marked affection is present it should be treated in the 
hope that the general state will improve. This applies especially to 
anemia, rheumatism and gout. Arsenical preparations, including 
mineral waters which contain arsenic, frequently give surprising re- 
sults, but it is often best to save this resource and not place a fresh 
case upon it, for the patient quickly becomes tolerant to it. When 
there is urgent need that a patient be cleared up for the time being, 
arsenic pushed to the limit, combined with vigorous local treatment, 
may effect the desired result. It may be months before the patient 
Avill again respond to arsenic. Generally speaking, the local treat- 
ment of chronic eczema may always be essayed in psoriasis. Many 
insist that alkalies have a distinct ability to control the disease ; this 
might be true of paroxysms, but alkalies are not suitable remedies to 
give for months. The benefit ascribed to iodide of potassium may be 
due to the alkali and not the iodine. The effect of alkalies may be 
secured by a diet made up largely of fruits and vegetables, by alkaline 
waters, etc. Alkalies and arsenic given simultaneously may prove 
more efficacious than either one alone. They may be pushed together 
or alternately. 

Local treatment is all-important and must be applied with refer- 
ence to every detail. Some of the agents in conunon use stain the 
hair, clothing and bedding. It is not well to use the best ammunition 
in incipient or mild cases, for the skin soon acquires a tolerance to 
remedies. As a rule, scales must be removed in connection with the 
treatment, so that the affected epidermis may be directly acted upon. 
To insure this result, bathing, oils and salicylic acid ointment cooper- 
ate. If a considerable area is involved, a general alkaline-starch bath 
may be used. Oil inunctions also serve to loosen the scales. The 
mere removal of the scales sometimes gives the impression of great 
benefit, and salicylic acid is valuable in preventing the reappearance 
of scales. For circumscribed patches on the knees and elbows, an 
ointment of white precipitate may be sufficient for a cure ; and it is 
better at the outset to use minerals, and especially tarry preparations, 
saving those to be named later for emergencies. In fact, any of the 
remedies found useful in chronic eczema should be of use in psoriasis, 
although the latter will prove much more refractory. 

The so-called specifics, chrysarobin and pjTogallol, ■will liave 
plenty of opportunity for full testing. Either of these in ointment 
form will cause the disappearance of psoriatic patches, but must not 
be used too often, lest the effect be lost. Remedies like these cannot 
b'e used in rotation very long, as both soon lose their effect. It is 

67 



well, as soon as a good impression is made with these, to go back 
to tar and mercurials. Betanaphthol is said by some to be nearly as 
good as the two remedies mentioned.

Eczema Seborrhoicum 

Synonyms: Dermatitis seborrhoica, Seborrheic eczema 
Plate 39, Fig. 63; Plate 40, Figs. 64 and 65; Plate 41, Fig. 66 

This affection comprised originally no more than the so-called 
"inflamed seborrhea" — salmon-colored disklike areas covered with 
a greasy scale and occurring on the head and face, sternal and intra- 
scapular regions. Exceptionally this eruption had a general distri- 
bution and bore a more or less striking likeness to a disseminated 
guttate psoriasis. Upon this substratum Unna proceeded to erect 
a superstructure of disease termed by him seborrheic eczema, which 
could be so stretched as to include a great deal of what is usually 
classed as ordinary eczema. Much of ordinary dandruff belongs 
here, the mere production of the fatty scales being held to be sufficient 
evidence of the disease even in the absence of sensibly inflamed 
scalp. A large part of the ordinary eczema of the scalp is also 
placed here, even if it be typical. In some of these cases the presence 
of ordinary inflamed seborrhea of older authors is present and fre- 
quently extends from the hairy scalp upon the smooth skin for a 
short distance. The middle of the face — sides of the nose chiefly — 
is a common site of inflamed seborrhea, the skin being oily, the 
sebaceous glands patulous and often occluded with sebum, \\dth 
maculopapular lesions of pale hue and surmounted by scales or fatty 
crusts. These lesions have affinities with acne rosacea and lupus 
erythematosus, and in fact the same lesion may be common to all un- 
der certain conditions. The obstinate eczema of the vermilion border 
of the lip is also claimed as seborrhoic, when it is associated with 
seborrhea of the scalp or nose. 

The peculiar lesions over the sternum and between the scapulae 
have usually passed for eminently characteristic local eruptions, quite 
peculiar to the localities affected. They are of common occurrence, 
and when we see them we may usually take it for granted that the 
subject has dandruff and seborrhea of the face. 

Patches are also not uncommon in the armpits and genitocrural 



region. While in some cases the discrete, pale-red lesions are in evi- 
dence, there are others in which the eruption resembles an ordinary 
eczema or intertrigo. A diagnosis can only be made through col- 
lateral evidences of seborrheic dermatitis elsewhere. 

As already stated, a diffuse, generalized case, where guttate le- 
sions are found over the limbs as well as the trunk, bears a striking 
resemblance to a psoriasis, which is either less scaly than common 
or has been benefited by treatment. In some of these cases, however, 
diagnosis is easy, for there are principal lesions in the favorite 
localities of seborrhoic dermatitis ; the lesions have a peculiar salmon 
color, and the scales are greasy. Eczema seborrhoicum of the scalp 
is a fertile cause of premature alopecia. 

Etiology 

It was long held that in ordinary functional seborrhea the 
process might culminate in a sort of adenitis of the sebaceous glands ; 
in the same manner, perhaps, as congestion of the sweat-glands 
leads to prickly heat. This view was succeeded by one involving in- 
fection of the glands from without, and resulting dermatitis. The 
suggestion of parasitism is much stronger here than in ordinary 
eczema. The claim has been advanced that the sweat-glands are also 
involved. Numerous microorganisms have been accused of causing 
this affection. No progress has been made of recent years in our 
knowledge of the latter, which for the present is very defective. 

Diagnosis 

The diagnostic features have already been enumerated in part. 
The disease, wherever else present, may always be found in the 
scalp; it begins there, and may not appear elsewhere. It seems to 
extend downward, for its next most conspicuous place is the face and 
about the ears, then the breast, axillae and back, and so on. The soil 
in which the disease develops is much like that in acne, the sebaceous 
glands evidently being strongly disposed to inflame. The inflamma- 
tion is mild in degree, focal, and produces greasy crusts. Itching is 
not extreme, and scratch-marks are seldom seen. Wlien it does 
closely simulate ordinary eczema, the locality and soil may be suffi- 
cient to exclude the latter. 

A most important source of confusion may arise in the case of an 
early syphilide, because the latter produces a very similar appear- 
ance in the scalp. A generalized case may also resemble a syphilitic 
outbreak. Syphilis, psoriasis, and a partially cured ringworm may 

70 



all simulate seborrhea, since all may form annular lesions. A good 
diagnostic resource is response to treatment, which should be much 
more prompt in seborrhea. 

Prognosis 

A tendencj' to recurrence after the disappearance of the lesions 
suggests a reinfection, and renders the course uncertain and chronic. 

Treatment 

Sulphur locally is regarded as a specific, although not much used 
in the scalp. The principle upon which sulphur is used is its effi- 
cacy in acne. Other valuable remedies are salicylic acid and resorcin. 
The general health should receive attention. Some individuals can- 
not use alcoholics without greatly aggravating seborrhea of the scalp. 
If the disease proves obstinate, any of the measures used in obsti- 
nate cases of eczema and psoriasis may be used, and the same is true 
of the treatment of the acnes, which may also be employed wdth the 
idea of rendering the sebaceous glands less disposed to inflame.

Pernio 

Synonyms: Chilblains, Erythema pernio 
Plate 42, Fig. 67 

Chilblains, unless severe, do not claim much attention, since they 
are an almost universal consequence of the seasons — the beginning 
and duration of the cold weather, at the close of which they subside of 
themselves. But conditions strongly suggestive of chilblains, since 
they involve the chilblain area, and also much influenced by cold 
weather, begin like ordinary chilblains. We refer here to Raynaud's 
disease and lupus pernio. The chilblain area comprises the extremi- 
ties of the body — the fingers, toes, heel, nose and ears. It is usually 
taken for granted that a person who suffers much from chilblains has 
a poor circulation and is anemic ; and doubtless the truth of this claim 
might be readily demonstrated. As a matter of fact, however, one of 
the most if not the most striking factor in keeping up the condition 
of chilblains is the sudden warming of chilled or damp feet by placing 
them before a tire or standing on registers. If there is a predisposi- 
tion, whether due to defective circulation or anemia, a slight degree of 
chilling may start up the affection. It is claimed by some authorities 
that chilblains are to a certain extent a familial affection. 

The skin in the chilblain area is cold to the touch, red or livid and 
edematous. Itching is intense, and increased by warm rooms, contact 
with bedding, etc. The impaired vitality of the tissues is shown by 
the readiness with which they form abrasions, blisters and ulcers, 
which heal with difficulty. 

Treatment 

Chilblains may be prevented by treatment instituted before the 
cold weather begins. Tonics should be given, and an attempt made to 
harden the tissues with cold bathing. Itching should be controlled by 
ordinary antipruritics. Anything which antagonizes the condition of 
stasis should be of value.

Raynaud's Disease 

Plate 42, Fig. 68 

This affection is a vasomotor neurosis which is described at great 
length in works on neurology and in special monographs. It belongs 
to the so-called acroneuroses and is therefore limited to the extremi- 
ties — fingers, toes, ears, and exceptionally the tip of the nose. It is 
believed to result from a persistent angiospasm of the terminal arter- 
ies and veins, although the same condition may be produced by an 
actual arteritis. It stands in a certain definite relationship to the so- 
called chilblain area, and appears to attack individuals with a sluggish 
terminal circulation who are predisposed to cold extremities and chil- 
blains. The persistent vascular disturbances tend to terminate in 
extensive trophic alterations, the most significant of which is dry gan- 
grene, Avhence the sjaionym "symmetrical gangrene." One or more 
digits may be involved on each hand or foot. 

The early sjonptoms vary considerably, due no doubt to the rela- 
tive part played by the arterioles and venules, and also to the fact that 
the initial spasm of the vessels may be followed by paresis. Further, 
the affection develops in a series of exacerbations with quiescent in- 
tervals between. The fingers are often seen to be white and cold, this 
phase of the process indicating intense local anemia from angiospasm 
of the arterioles. This stage is by no means necessarily present, and 
the malady may begin witli what is termed the second stage. It is 
impossible to state to what extent this is due to venous angiospasm. 
The fingers become red and congested, as if from the cold, the color 
usually deepening as the disease advances. Even in the early period 
the extremities may have an intense cyanotic hue. The statement 
that angiospasm is necessarily followed by a condition of vascular 
relaxation does not seem reasonable, for the vascular changes must 
be essentially obstructive in order to cause gangrene. The latter is 
not a necessary development, for the condition may never progress 
thus far. The gangrene may also be very sliglit and superficial or, in- 
stead of necrosis, trophic ulcers or atrophy may develop. It must 



never be forgotten that Raynaud's disease is not infrequently com- 
bined with one of the other acroneuroses, notably scleroderma, ery- 
thromelalgia, and perhaps acroparesthesia. These complications 
naturally give rise to atypical cases. The uncomplicated disease is 
not characterized by much subjective disturbance. 

Diagnosis 

It is often difficult to distinguish Raynaud's disease at its outset 
from the other acroneuroses. As already stated, transition forms 
occur, and the different affections really form a group disease. There 
is considerable resemblance at times to the lesions of syringomyelia. 
It has been said that Raynaud's disease cannot possibly be distin- 
guished from s>i5hilitic arteritis, the crippling of the peripheral cir- 
culation being practically the same. Arteritis of some sort is no doubt 
responsible for a certain per cent, of cases. A Wassermann test 
should be made as a matter of routine. 

Prognosis 

This is good for life, but rather poor for recovery. The gangre- 
nous tissues separate in time, and the exposed surfaces heal slowly. 
Amputation is seldom required. The disease may reappear in other 
fingers, so that we may see the different aspects side by side. 

Treatment 

This includes all measures which may favorably modify the cir- 
culation, including general regimen. Hydrotherapy, massage, galvan- 
ism and faradism have all been used extensively. In the later stages 
strict asepsis is required, as infection from without readily occurs and 
fatal sepsis has been known to result.

vanced diabetes mellitus. The extremities are generally affected, par- 
ticularly the toes and fingers. Occasionally the penis is involved. 
Although the gangrene may be of any familiar type, Kaposi has 
described a form believed to be peculiar to this affection. It is seen 
only in advanced cases, and consists of a serpiginous grouping of bul- 
lae occurring on the limbs in successive crops. A black scab then 
forms, which is surrounded by a ring of new bullae. The corium is 
involved, and after all scabs have come away, a portion of it sloughs. 
This, in turn, being thrown off, leaves a granulating surface. 

Prognosis 

This should always be guarded, as the gangrene occurs only in 
individuals suffering from advanced diabetes. 

Treatment 

This has never been very satisfactory. For the underlying condi- 
tion, general medical and dietetic measures are of course indicated. 
When gangrene is established its advance is often controlled by the 
frequent application of warm antiseptic dressings. In beginning dia- 
betic gangrene of the fingers good results have recently been reported 
following the employment of Schaeffer's hot air method of treatment. 
The intense heat is said to force new blood into the stagnating blood- 
vessels and by re-establishing the circulation aborts the process.

Ecthyma Gangrenosum 

Synonym: Dermatitis gangrenosa infantum 
Plate 44, Fig. 70 

This affection, while peculiar to young children, corresponds to 
multiple spontaneous gangrene in adults. A study of the literature 
conveys a strong impression that a distinct disease as described by 
some authors does not really exist. If we state that in certain cachec- 
tic infants nearly any eruption may become gangrenous under certain 
unknown conditions, there is not much to add. 

Hutchinson first described the condition as a sequel of varicella, 
under the name varicella gangrenosa. A similar termination was 
noted in vaccinia. Other cases were described as pemphigus gan- 
grenosus. French authors regard it simply as ecthyma with a ne- 
crotic tendency, and term it terebrant or boring ecthyma, rather than 
gangrenous ; for in gangrene we naturally expect to see more lateral 
extension. The term rupia escharotica conveys the impression of 
firmly adherent crusts, beneath which necrosis occurs, either from 
pressure or through the action of anerobic bacteria. 

The chief interest lies in the purely spontaneous cases, which are 
said to begin as small papulopustules or vesicles about the buttocks. 
In a case described a few years ago by Welander, in a young infant, 
the head was the seat of the lesions, although the statement has been 
made that the head is never attacked. The disease may run a rela- 
tively mild or a severe and fatal course, and there may be only a few 
lesions or many. It has been shown to be independent of tuberculosis 
and also of syphilis. No evidence of pathogenic germs constantly 
present has been adduced, nor is it even known whether such germs 
are inoculated from without or gain the surface from within. In fatal 
sepsis a few small necrotic pustules have been seen in the skin as if 
produced by emboli of germs, but they bear no clinical relation to 
this affection. 

From the fact that the lesions are usually seen about the region of 

70 



Plate 44. 




Fig. 70. Ecthyma gangrenosum. 



the buttocks, it has beon thought that they have resulted from inocula- 
tion from feces or other outward source. They have, however, been 
seen to cover the abdomen and limbs, also, as above stated, the head. 
To sum up, when the affection is not secondary to some well- 
knowTi eruption, like varicella, it appears to begin as papulopustules 
or vesicopustules, which lead to crust-formation. Destruction of tis- 
sue takes place beneath and around the crusts and an ecthymatous 
lesion is produced, i.e., a large pustule with a hard, inflamed base. 
The crusts come away, leaving ulcers, which, if the lesions are close 
enough together, may become confluent, but no diffuse gangrene 
results. Permanent scars naturally result. 

Treatment 

This is carried out by ordinary antiseptic dressings, with tonics 
and good nursing.

Ulcer from Roentgen Rays 

Plate 45, Fig. 71 

The Roentgen rays cause various degrees of injury to the skin 
and subjacent tissues, as a result either of oversensitiveness or ex- 
cessive dosage, the latter being largely preventable, as should also be 
the results of accidental exposure. The changes caused somewhat 
resemble the different degrees of sunburn, and there are also trophic 
alterations, such as shedding of the hair. After a period of latency, 
occupying in some cases several days, the characteristic erythema or 
dermatitis supervenes. The mildest degree is much like the erythema 
due to the solar rays and likewise tends to leave pigmentation. With 
repeated or severe exposures or undue sensitiveness a vesicular der- 
matitis results. Unlike sunburn, a deeper degree of injury sometimes 
occurs in which superficial necrosis develops, leaving a large raw sur- 
face covered perhaps with an adherent false membrane. These are 
not only extremely painful but show little or no tendency to cicatrize. 
There is also, so to speak, a fourth degree of injury, in which the 
subcutaneous tissues — muscles, bone, etc. — may also slough, leaving 
deep losses of substance. Hence the two severe degrees of X-ray 
injury are not unlike burns of the third and fourth degrees. They 
appear to be due primarily to injury to the blood-vessels. Those who 
work continually ■\\ath the rays also suffer from atrophy of the skin 
of the hands and forearms, and the development of epithelioma is not 
infrequent. 

Treaimeni 

The milder degrees of injury are managed like dermatitis and 
acute eczema. The ulcers are often very painful and anodjmes are 
frequently indicated, orthof orm being the most useful. In deep ulcers 
excision followed by skin grafting may be practiced but owing to the 
peculiar pathological change that has taken place in the tissue sur- 
rounding the ulcer the surgical results are often disappoiiating.

Pellagra 

Plates 46 and 47, Figs. 72 and 73 

Pellagra is a general disease with important and characteristic 
cutaneous manifestations which serve for its recognition. It was at 
first thought to be peculiar to certain countries in southern Europe, in 
which it is endemic, notably parts of Spain and Italy. In compara- 
tively recent times it has been seen both sporadically and epidemically 
in various localities in both hemispheres. It is clearly not peculiar to 
warm climates, although practically confined to them. The earliest 
cases seen in the United States were in native subjects, and confined 
to the insane. They are known as, or presumed to have been, pellagra 
from the records of institutions, although not recognized at the time. 
In quite recent years a few imported cases have been noted in the 
United States. The great bulk of American cases, however, have 
appeared within the last decade, and in the Southern States, where 
pellagra now prevails to an alarming extent. It has recently been 
asserted that the disease may be found described in the annals of 
Spanish America at a date much earlier than the oldest European 
records. 

Owing to its severe constitutional symptoms, chiefly manifested in 
the nervous system and gastro-enteric tract, pellagra is relatively un- 
important as a dermatosis. A large proportion of cases find their 
way to insane asylums. The eruption of pellagrins is confined to a 
desquamating erythema of the face and backs of the hands and 
wrists, which extends for a variable distance up the forearms; this 
is a chronic condition which in time shows a slight degree of thicken- 
ing and deposition of pigment. A certain amount of atrophy may 
remain. 

The patient seems at first to suffer from spring lassitude along 
with disordered digestion. The latter may involve almost the entire 
digestive tract — stomatitis, epigastric pain, anorexia, and diarrhea. 
The patient becomes weak and easily fatigued. After several weeks 
of these prodromes, the parts exposed to the weather — face, portions 
of the upper extremity already mentioned, and the tops of the feet 
and ankles, in those exposed, assimie a deep red hue with a tendency 
to become brown. That the sun and wind are only predisposing 

79 



causes, as in the case of freckles, is apparent from the fact that in 
rare instances the erythema has been seen on non-exposed regions. 
The process may be very superficial or deeper, and in the latter case 
results in more or less thickening. Peeling, pigmentation and atro- 
phy, these sequelae of the inflammatory process, are often seen side 
by side, forming a picture which could not be mistaken for any other 
affection. The skin, thinned and wrinkled, and deeply pigmented, 
sometimes shows diminished sensibility. The amount of cutaneous 
participation is no index of the general severity of the disease. In 
the more acute forms the patient may die before erythema develops. 
The course of the skin lesions follows the seasons, improving or dis- 
appearing in the fall, probably to reappear in the spring. The peeling 
is an integral part of the disease and not a mere sequel of the 
erythema. Even when the skin has become atrophic the epidermis 
comes away in large flakes. Several years are required for the com- 
bined cycle of changes in the skin. The patients are doomed to 
disability and very often to early death. There are, however, degrees 
of severity and in the mildest the patient may live for many years 
and sometimes recover. In a virgin community the disease is more 
severe and few survive. 

Etiology 

Of this absolutely nothing is known. It is probable that two fac- 
tors act in association. One is a living cause, and the other a vehicle 
which is probably articles of diet. The spoiled Indian meal so often 
accused cannot cause all the cases. We know now tliat the prosperous 
and well-fed may become affected. It is believed that solar rays are 
somehow responsible, in that they may liberate a poisonous principle 
in the tissues. As a pseudo-pellagra has been caused by various 
agencies — alcoholism, and perhaps ergotism — it has been held that 
pellagra is a mere syndrome. The actual lesions which cause death 
seem to be intracranial — pachymeningitis and cerebral sclerosis. 

Diagnosis 

Only in the early stage could any confusion arise. The disease 
while it may attack all ages is not a child's malady, but inclines to 
affect matured people exposed to the weather. No one should con- 
fuse pellagra with sunburn, for it appears in the spring and not at the 
beginning of summer. We sometimes find a crude simulation of 
pellagra in wretched cachectic and alcoholic subjects. 

Treatment 

On the first appearance of the disease when the type is mild, vigor- 
ous constitutional treatment with change of diet and surroundings 

80 



ought to benefit the patient. Arsenic and thyroid substance are two 
remedies which are believed to have some specific virtues. That a 
severe blood dyscrasia is present seems to follow from the favorable 
results of transfusion in severe cases. Local treatment is hardly 
mentioned by authors; but as considerable itching is present the 
management of acute eczema ought to be transferable to pellagra.

Variola 

Synonym: Smallpox 
Plate 48, Fig. 75 ; Plate 49, Fig. 76 

Variola is an acute infectious disease of unknown causation: a 
protozoon has been described but has not been definitely proven to be 
the causative agent. 

Among those unprotected by vaccination, variola is the most viru- 
lent of all contagious diseases. 

The period of incubation, when the disease is inoculated, is eight 
to nine days ; when it is transmitted by contagion, it is ten to fourteen 
days, and occasionally longer. All persons exposed should be kept 
under observation for at least three weeks. 

Onset is sudden with severe chills, high fever, temperature 103° 
to 105° F., intense backache and pains in the legs, vomiting, frequently 
delirium and in children convulsions. 

Prodromal eruptions, when they occur, appear usually on the sec- 
ond day. They may be morbilliform or erythematous in character 
and may be hemorrhagic, and are most marked on the lower part of 
the abdomen, inner surface of the thighs, the axillae or lateral thoracic 
region; occasionally they occur on the extensor surfaces, especially 
of the knees and elbows. The erythematous type limited to the lower 
part of the abdomen and inner surface of the thighs is seen especially 
in pregnant women. 

The characteristic eruption appears on the fourth day, first on 
the forehead and face, and spreads rapidly over the whole body, in- 
volving the mucous membranes of the eyes, mouth, and throat; but 
it is always most marked on the face and hands. The eruption con- 
sists at first of hard, small, shotlike papules which rapidly increase 
in size and gradually, usually by the end of the second or third day, 
become vesicular. These vesicles are always umbilicated, and after 
another two or three days their contents become purulent. As the 
pustules develop, the temperature, which had gone dowoi with the 

82 



Plate 48. 




_o

bJO 



development of the papules, rises again. The pustules begin to dry 
up and crust in about ton days. 

At this time the temperature falls and there is a general improve- 
ment of all sjTiiptoms. The crusts usually come off and leave com- 
pletely healed lesions by the twenty-first day. 

In addition to the above or regular tj^De we have hemorrhagic 
smallpox, which occurs in two forms: first — purpura variolosa: in 
this form at the end of the second or on the third day an ervthematous 
rash appears, especially in the groins, with small punctiform hemor- 
rhages; the rash extends, rapidly becoming more and more hemor- 
rhagic, ecchymoses appearing in the conjunctiva — and hemorrhages 
from mucous membranes. This tj-pe is rapidly fatal — death occur- 
ring on the third to fifth day. Second form or variola hemorrhagica 
pustulosa: in this form hemorrhages occur when the rash reaches 
the vesicular or pustular stage. Bleeding from mucous membranes 
is common and the mortality is high — death occurring on the seventh 
to ninth day. Occasionally cases are seen where bleeding takes place 
into the lesions in the vesicular stage, followed by rapid abortion of 
the rash and speedy recovery. 

Varioloid, modified smallpox, seen in persons who have been suc- 
cessfully vaccinated, sets in abruptly like the regular type, but the 
sjTnptoms are usually milder, the number of the lesions are very 
much less and may be limited entirely to the face and hands; the 
temperature drops rapidly, the lesions soon dry up and there is no 
secondary fever. 

Diagnosis 

The prodromal rashes are to be differentiated, first, from measles 
by the severity of the constitutional sjTnptoms, the absence of 
Koplik's spots, the absence of lacrjination and coryza, and by the 
early appearance of the rash on the trunk instead of on the face and 
neck as in measles. Secondly, from scarlatina by the initial symptoms 
and the absence of the angina and scarlet tongue. 

The regular rash must be differentiated chiefiy from varicella. 
This is done by the severity of the onset, the duration of the prodro- 
mal SjTnptoms, the site where the rash first appears — in varicella the 
rash first appears on the trunk — and the indi\'idual characteristics of 
the lesions. The papules in variola are always hard and shotty and 
last about two days ; in varicella the papules are not indurated and be- 
come vesicular in a few hours. The vesicles of variola are always 
umbilicated and do not collapse when ruptured ; in varicella they may 

83 



be umbilicated, but they are superficial and do collapse when rup- 
tured. The most characteristic and important point, however, is that 
the lesions in variola are all in the same stage on the same site, while 
in varicella the lesions come out in crops, and we find papules, ves- 
icles, pustules and crusts intermingled in the same region. The 
lesions in variola are comparatively most numerous on the face and 
hands — in varicella they are comparatively most numerous on the 
back. 

From pustular syphilis it is diagnosed by the history of the onset, 
the history of the development of the rash — the absence of mucous 
patches and condylomata. A negative Wassennann would also be of 
great aid in the diagnosis. 

Prognosis 

In the hemorrhagic types it is very bad. In the regular type it 
varies directly with the severity of the disease, from bad in the con- 
fluent form to favorable in the discrete form. In varioloid it is very 
good. 

Prophylaxis 

Everyone should be vaccinated regularly every three or four 
years, and if exposed to the disease revaccination is imperative. 

To prevent the spread of the disease, all cases occurring in cities 
or thickly settled communities should be isolated in suitable hospitals. 
All persons exposed should be inspected daily for at least twenty- 
one days. 

All bedding and clothing that has come in contact with the patient 
should be thoroughly disinfected either by boiling or steam steriliza- 
tion. If this cannot be done, it should be burned. The premises from 
which a case has been removed should be fumigated with either sul- 
phur or formaldehyde, using four pounds of sulphur for every 1,000 
cu. ft. of air space and eight hours' exposure or six ounces of formalin 
per 1,000 cu. ft. of air space and five hours' exposure. After fumiga- 
tion the premises should be washed with a 1 to 1000 solution of 
bichloride of mercury. All excreta should be sterilized with a 5% 
solution of phenol or a 1 to 1000 solution of bichloride of mercury. 

In case of death the body should be wrapped in a sheet saturated 
■with a 1 to 1000 bichloride solution and interred in a metal lined coffin. 

Treatment 

Absolute rest in bed from the beginning until the secondary fever 
lias subsided. The diet during this period should be liquid. 

84 



For the intense headache and backache morphia by hypodermic 
injection gives the best result and should be given early. Dover's 
powder is occasionally satisfactory in relieving the insonmia. The 
temperature can be best controlled by hydrotherapy. 

The eyes must be kept scrupulously clean by repeated Avashings 
with boric acid solution. For the nose and throat a dilute Dohell's 
solution or a 2% boric acid solution is useful. 

Scrupulous cleanliness is absolutely necessary during the whole 
course of the disease and the patient should receive daily baths, tak- 
ing care not to rupture the vesicles or pustules on the face. 

The red light treatment has received considerable attention re- 
cently; to be of any value it must be carried out absolutely, making 
it necessary to have only red glass in all -windows and lighting fix- 
tures, and a vestibule with double doors so that not a single ray of 
white light can enter the room or ward. The red light is very 
trying on the eyes of both patients and attendants, and the results 
hardly justify the inconvenience it causes. 

The prevention of scarring is practically impossible, but carbol- 
ized ointments or lotions should be applied to the face to relieve the 
intense pruritus. 

During the stage of pustulation, stimulants are almost always 
necessary: the best are whiskey and strychnine; to an adult half an 
ounce of whiskey and strj'chnia sulphate gr. Ho can be given every 
four hours. 

The delirium is best treated by bromides and morphia. 

The crusts, which are usually ready to come off in twenty-one 
days, should be completely removed before the patient is discharged ; 
but care must be taken to see that no moist or raw spots exist and 
that all crusts have been removed from the palms and soles and from 
under the edges of toe and finger nails. 

Complications 

Purulent conjunctivitis is frequent and is to be avoided by fre- 
quent and careful cleansing of the eyes. "WTien it develops it is to be 
treated the same as conjunctivitis from any other cause — cold com- 
presses — ^boric acid washings sufficiently frequent to keep the eyes 
clean. Solution of argyrol (20%) every four hours or a 1% to 
2% solution of silver nitrate painted over the conjunctiva once or 
twice a day. If a keratitis sliould develop the cold compresses should 
be changed to hot ones — the pupils must be kept dilated with a 1% 
solution of atropine sulphate. The cleansing with the boric acid solu- 

85 



tion is to be continued, and if corneal ulcers develop it may be neces- 
sary to cauterize them with tincture of iodine or the galvano cautery. 

Laryngitis is frequent and may cause necrosis of the cartilages 
and be followed by broncho-pneumonia, or may cause edema of the 
glottis, necessitating tracheotomy; intubation is not satisfactory in 
these cases. The throat complications are best avoided and treated by 
spraying or gargling with aUcaline solutions or with a hot normal salt 
solution. In beginning edema of the glottis an ice collar is frequently 
of service, at other times hot poultices seem to give better results. 

Otitis media sometimes occurs. As soon as the drum membrane 
is red and bulging it should be incised and the ear irrigated with hot 
boric acid solution sufficiently often to keep it clean. If tenderness 
develops over the mastoid it should be opened at once, the mastoid 
cells completely removed and the antrum drained. 

Albuminuria is frequent, but a true nephritis is rare ; if it occurs, 
however, the patient should be given plenty of pure water and placed 
on a milk diet; diuretics are seldom necessary. If suppression of 
urine develops, hot packs and high saline irrigations are indicated. 
In robust patients bleeding is often of considerable benefit. 

Multiple abscesses are frequently seen and are at times extremely 
troublesome. They should be opened as soon as fluctuation is de- 
tected, drained, and packed. 

The characteristic pitting that is often such a disfiguring sequelae 
to the disease, is always permanent. Treatment is most unsatisfac- 
tory. Fibrolysin and thiosinanim are useless and massage and 
electrical applications of but little, if any, benefit.

Varicella 

Synonym : Chicken-pox 

Plate 48, Fig. 74; Plate 49, Fig. 77; Plate 50, Fig. 78 

This is an acute contagious disease of unknown causation, having 
a period of incubation from ten to fifteen days. Although generally 
regarded as an affection of childhood, its occurrence in adults is not 
as rare as is commonly supposed. 

The prodromal symptoms are of short duration, lasting as a rule 
but a few hours. They consist of slight fever, chilliness, nausea, with 
occasional vomiting, pain in the back and legs, and very rarely 
convulsions. 

The eruption generally appears first on the back or chest, although 
frequently first seen upon the face. It consists of small superficial 
papules which rapidly become vesicles, and at the end of about thirty- 
six hours after the first appearance of the rash the contents of these 
vesicles have become purulent. The vesicles are often ovoid in shape, 
very superficial, and the skin around them is neither infiltrated nor 
hyperemic. Occasionally some of the vesicles are found to be um- 
bilicated. During the third and fourth day the lesions dry up and are 
covered wdth a browmish crust which soon falls off, and as a rule 
leaves no scar. Fresh crops of papules continue to develop during 
the first three days, giving the characteristic picture of intermingled 
papules, vesicles, pustules and crusts. 

The lesions are most numerous on the trunk, but the extremities, 
face, and scalp are also affected. They are seldom seen on the palms 
and soles, although they occur here in severe cases. The lips and 
mucous membranes are sometimes involved as illustrated in Fig. 
74. Occasionally the vesicles become very large and develop into bul- 
lae (varicella bullosa) and in certain severe cases cutaneous ecchy- 
moses and bleeding from the mucous membranes occur (varicella 
hemorrhagica). 

In delicate and especially in tubercular children the lesions may 
become gangrenous and large areas of skin may be destroyed. The 

87 



gangrenous spots are usually circular in shape, and as a rule they 
vary from a quarter to three-quarters of an inch in diameter. They 
have clear cut vertical edges and appear as though a piece of skin 
had been removed by a small cutaneous punch. The disease may 
recur, as many as three attacks having been reported in the same 
individual. 

Diagnosis 

This, in typical cases, occurring in children, presents but few diffi- 
culties, but in severe cases in adults it is likely to be mistaken for 
variola or varioloid. The principal differential points are the short- 
ness and comparative mildness of the prodromal symptoms, the rela- 
tively larger number of lesions on the trunk, especially on the back, 
the absence of infiltration In the lesions, their sui^erficial character, 
the rapid development of the lesions from papules to pustules, their 
development in crops, and lastly, the intermingling of papules, ves- 
icles, pustules, and crusts on the same area. 

Prognosis 

This is always favorable even in severe cases in adults. 

Treatment 

Entirely symptomatic. If there is much elevation of temperature, 
the patient should be put on liquid diet and kept in bed for a few 
days. A single good dose of castor oil or repeated small doses of calo- 
mel with sodium bicarbonate may be given. If there are many vesi- 
cles on the face, efforts should be employed to prevent subsequent 
pitting. 

External applications of alcohol may be used for its drying effect 
on the papules and protective dressings similar to those recommended 
in variola may be used to prevent the scratching and the secondary 
infection which is invariably the cause of the pits.

Vaccinia 

Plate 51, Figs. 79 and 80 

This is the term applied to the exanthem produced by the inocula- 
tion of bovine virus. On the second, third or fourth day after vac- 
cination there appears at the site of inoculation a slightly elevated 
papule, surrounded by a reddish zone. This papule becomes vesicular 
on the fifth or sixth day, and reaches its maximum size on the eighth 
day when it is a large, tense, umbilicated vesicle one fourth to one 
half of an inch in diameter with a hard and prominent margin, filled 
with a limpid fluid and surrounded by a wide inflammatory areola. 
Its development is accompanied by general malaise, fever, tempera- 
ture, 101° to 104° F., which usually lasts four or five days, and swell- 
ing and soreness of adjacent lymphatic glands. After the tenth day 
the vesicle begins to desiccate and by the fourteenth day is covered 
by a thick, firm crust, which falls off after a period of from one to 
three weeks, leaving a sharply defined pitted or honeycombed scar. 
Constitutional sjTnptoms are less severe in children under one month 
than in those of five or six months ; and infants should be vaccinated 
as soon as nutrition is established, usually in the first three months. 
As a rule it should be avoided during dentition. 

Generalized vaccinia may be either local or constitutional. The 
former is due to repeated inoculations, the vaccination repeating it- 
self at each point of inoculation. It is seen especially on the face and 
genitals ; and sometimes there is an outbreak of lesions over the whole 
body, accompanied by severe constitutional s>inptoms. This type is 
usually seen in the second or third week. In constitutional general- 
ized vaccinia, vesicles are frequently seen in the neighborhood of the 
primary sore, but the true generalized vaccinia of systemic origin, 
with lesions developing on different parts of the body, is rare. The 
lesions are most numerous on the vaccinated limb ; they may be few 
or many. Each lesion pursues the course of the typical primary vac- 
cination. The vesicles usually develop from the eighth to the tenth 
day, and they may continue to develop in crops for five or six weeks 

89 



after vaccination. Generalized vaccinia has occurred in children fol- 
lowing the ingestion of powdered crusts from a vaccination lesion. 

Diagnosis 

The history of a recent vaccination should render the diagnosis 
easy even in complicated cases. 

Prognosis 

Constitutional symptoms associated with generalized vaccinia in 
children may be very severe, and deaths have been reported, but ordi- 
narily the prognosis is favorable. 

Prophylaxis 

Delicate children and infants in poor health should not be vac- 
cinated until their general condition has been improved and children 
suffering from itchy skin diseases as eczema, urticaria or scabies 
should not be vaccinated until the eruption is quite cured. Vaccina- 
tion pustules should be covered by a dressing or shield so that the 
child is unable to scratch or pick it. 

Treatment 

There are seldom any indications for internal medication. The 
affected areas should be covered with wet compresses. Solutions of 
boric acid or acetate of aluminum are the ones most generally rec- 
ommended. As the condition improves a weak ichthyol ointment 
may be substituted for the wet dressings.

Synonyms: Measles, Rubeola 
Plate 52, Figs. 81 and 82 

Tliis is an acute contagious eruptive fever of unknowTi causation. 
The period of incubation is from ten to fourteen days, but may be 
as long as eighteen or twenty days. The disease begins with catarrhal 
symptoms — sneezing, coughing, injection of the conjunctiva, lacryma- 
tion and rise of temperature to about 103° F. 

On the second day usually there appear on the buccal mucous mem- 
brane and inside of the lips small irregular spots of a bright red color. 
In the centre of each spot is a minute bluish white speck. They 
lose their characteristic appearance, however, as the eruption on the 
skin develops. These are the Koplik spots and are of considerable 
diagnostic value. 

As a rule on the fourth day the eruption appears — first on fore- 
head and cheeks in the form of small red maculo-papules which 
increase in size and spread — the whole body being covered in twenty- 
four to forty-eight hours. The rash when fully developed consists of 
roundish, slightly elevated maculo-papules which vary in size from 
a pinhead to a finger nail, varying in color from a dark red to a 
purplish hue. They are frequently confluent on both the face and 
body, and have often been erroneously diagnosed as a mixed infection 
of scarlatina and morbilli. Hemorrhages into tlie lesions, especially 
on the lower part of the abdomen and thighs, are seen fairly fre- 
quently but do not add as much to the gravity of the disease as when 
seen in variola or scarlatina. Wliere the rash is confluent there is 
considerable swelling of the skin. The eruption begins to fade after 
two or three days, leaving brown pigmentation at the site of the 
lesions, especially on the trunk and limbs. 

The temperature, which reaches its greatest height with the full 
development of the rash, falls rapidly with the fading of the rash, to- 
gether with a subsidence of the catarrhal symptoms. 

91 



The amount of desquamation varies with the intensity of the rash 
and may not be seen at all in mild cases. It usually occurs in fine 
branny scales and is completed in from fourteen to twenty-one days 
after the appearance of the eruption. 

Prognosis 

This is favorable unless some serious complication develops. 

Prophylaxis 

AU cases should be properly isolated until desquamation is 
finished, and children in a family where a case exists should be 
excluded from school until the case has terminated. Bedding, carpets, 
etc., should be disinfected and the premises fumigated in a manner 
similar to that described under variola. 

Diagnosis 

In a well developed case this is very easy. It is diagnosed from 
rubella by the severity of the onset, its longer duration, the presence 
of Koplik's spots, coryza and conjunctivitis. The lesions of morbilli 
are larger and deeper in color than tliose of rubella, and the consti- 
tutional symptoms are always more severe. 

From scarlatina it is diagnosed by the character of the onset, its 
longer duration, the presence of Koplik's spots, the absence of severe 
angina and particularly by the character of the eruption, that of 
scarlatina being a punctate erythema. 

Treatment 

Kest in bed in a well ventilated room and liquid diet should be 
insisted upon as long as the temperature is elevated and the rash is 
present. The room should be darkened to protect the eyes. 

Baths are generally agreeable and should be given during the 
stage of eruption. 

The temperature is self -limited and usually requires no treatment 
beyond the baths. 

The eyes should be kept clean with a boric acid solution. 

If the cough is very troublesome a few small doses of heroin or 
codein may be given. 

Severe cases with cyanosis, high fever and cold extremities should 
have stimulants — whiskey and strychnia. An ice cap applied to the 
head is very agreeable, and hot mustard baths are often valuable in 
relieving pulmonary congestion. 

92 



Edema of the glottis occurs fairly often and may necessitate in- 
tubation or tracheotomj'. 

Membranous pharyngitis or laryngitis should be treated like 
other cases of pseudo-diphtheria. If the diphtheria bacillus is pres- 
ent, diphtheria antitoxin should be used the same as in a simple case 
of diphtheria. 

After recovery tonics as iron, quinia and strychnia are indicated 
and to delicate children cod-liver oil should be given during the fol- 
lowing cold season. 

The most serious sequela is tuberculosis either of the lungs or 
cervical glands and this unfortunately is seen quite frequently. A 
number of cases of lupus vulgaris have been reported as developing 
shortly after an attack of morbilli.

Rubella 

Synonyms: German measles, Rotheln 
Plate 53, Fig. 83 

Eubella is an acute contagious eruptive fever with an incubation 
period of from ten to twenty-one days. The period of invasion is very 
short, usually lasting only a few hours ; and in ntiany cases no prodro- 
mal symptoms at all occur. When they are present they consist of 
malaise, slight fever, and very mild catarrhal symptoms ; but there 
may, very rarely, be vomiting, convulsions, delirium, epistaxis, rigors 
and headache. 

The eruption appears first on the face and, spreading rapidly, 
covers the whole body in less than a day. Occasionally it comes out 
first on the back, or the whole body may be covered almost at once. 
In many cases the whole body is not covered, but the rash is seen 
most constantly on the face. 

The character of the eruption is quite variable. It is most fre- 
quently composed of small pinkish maculo-papules from a pinhead to 
a pea in size, frequently confluent on the face, forming large irregular 
blotches. On the trunk it is usually discrete, but there may be a 
uniform red blush, still the characteristic maculo-papules can be 
found on the forehead, wrists or fingers. The degree of elevation of 
the lesions is variable from being almost imperceptible to being so 
marked as to give the skin a distinctly shotty feel. The color also 
may vary from pink to a dark red and very rarely the rash may be 
hemorrhagic. 

Minute bright red points may be seen on the uvula and soft palate 
during the first twenty-four hours. 

The temperature is highest with the full development of the rash, 
and is 101° F. or less, but in the very rare severe cases it may be 
103° F. 

The rash is generally of two or three days' duration and is usually 
accompanied by moderate itching. The post cervical glands are 
always enlarged. They subside slowly without suppuration. 

94 



Plate 5: 




Fig. 83. Rubeola. 



Desquamation may be entirely wanting but usually occurs in the 
form of fine scales. 

Diagnosis 

Rubella is diagnosed from morbilli by its longer period of incuba- 
tion — shorter period of invasion — absence of Koplik's spots and its 
milder catarrhal and constitutional sjTnptoms. 

From scarlatina, by the absence of severe prodromal symptoms — 
the absence of angina — the presence of the typical maculo-papules on 
the forehead, wrists or fingers — and its longer period of incubation. 

In all cases, unless the disease is epidemic, it is not safe to make 
the diagnosis of rubella until the case has been under observation for 
some time. 

Treatment 

This is entirely symptomatic. A dose of calomel or castor oU 
at the beginning of the attack is practically all the medication re- 
quired. The patient should be isolated for about a week.

Scarlatina 

Synonym: Scarlet fever 
Plate 54, Fig. 84; Plate 55, Fig. 85 

Scarlatina is an acute contagious disease of unknown causation. 
It has been claimed that a streptococcus is the causative agent, but 
while this is associated with the complications, it is probably but a 
secondary or accompanying infection. The disease most frequently 
attacks children between two and ten years of age. Adults are less 
susceptible than children. Scarlatina is not as contagious as measles. 
Frequently only one child in a family where there are several children 
will contract the disease, while with measles practically all children 
exposed, unless protected by a previous attack, contract the disease. 

The period of incubation is usually from two to six days, but it 
may be as short as six hours or as long as two weeks; over seven 
days, however, is extremely rare. The onset is sudden, with a rise 
of temperature from 101° to 105° F., vomiting, sore throat and 
frequently in children, convulsions and delirium, the intensity of 
the symptoms varying with the severity of the attack. The vomiting 
is frequently persistent and without nausea. The throat symptoms 
may be so mild that they are only detected by examination, but in 
most cases there is a uniform redness of the whole pharynx, and small 
red points are seen on the hard palate and the patient complains of 
soreness and pain on swallowing. The tip and edges of the tongue 
are red and the centre is covered with a thick fur, through which the 
enlarged papillae project, giving it the so-called strawberry appear- 
ance. In severe cases the tonsils and fauces are markedly swollen and 
may be covered by a pseudo-membrane, which may extend from the 
posterior wall into the mouth or up into the nostrils and occasionally 
may involve the larynx, trachea and bronchi. The cervical glands are 
frequently enlarged and tender. 

The eruption usually appears on the second day, but it may 
develop within twelve hours, or it may be delayed until the fourth or 
fifth day. It appears first on the neck and chest and spreads rapidly, 

96 



Plate 54

involving the entire skin, in from fonr to twenty-four hours. It has a 
vivid scarlet hue and is conii)()sed of innumerable minute red points 
upon an erytliematous ground. Although seen upon the face there is 
a peculiar pallor around the mouth. Occasionally all of the skin is 
not involved, the rash occurring in patches, or the rash may not 
develop on the face, or it may be present only on certain parts, 
usually the groins, axilla;, flexures of the elbows, or upon the buttocks 
and posterior surface of the thighs. In some cases it is so slight 
and evanescent that it entirely escapes observation, or it may be 
entirely absent both in mild cases and in those with severe angina, 
and even in malignant cases it may never develop. Miliary vesicles 
are frequently seen, especially upon the chest and abdomen. Petechias 
are occasionally seen and in malignant cases they become very exten- 
sive. At the height of the eruption, the skin of the face and hands 
may be considerably swollen. Pruritus is variable, and at times may 
be quite marked. The rash may last from a few hours to about 
six days. 

The temperature is highest with the full development of the rash 
and in fatal cases may rise to 108° or even 109° F. The pulse varies 
from 120 to 150 or higher. In favorable cases it continues high for 
two to five days and falls by lysis. The vomiting usually stops with 
the development of the rash. The urine shows febrile characters and 
albuminuria is frequent. The tongue desquamates in a few days and 
is clean by the time the rash begins to fade. The desquamation of the 
skin is characteristic. It begins after the rash has faded, usually on 
the eighth to twelfth day, but may be delayed until the twenty-first 
day. It begins on the neck and chest and is flaky in character. On 
the hands and feet, where the epidermis is thickest, it is finislied last, 
and here the flakes are quite large, frequently the epidermis being 
shed almost entirely in a glovelike cast. It is usually completed at 
the end of thirty-five days, but may continue for seven or eight weeks. 

Diagnosis 

Typical cases present no difficulty; but in the mild and atypical 
ones the diagnosis is extremely difficult and at times impossible until 
the characteristic desquamation appears. The principal diagnostic 
symptoms are the vomiting associated with sore throat, and a punc- 
tate rash on the hard palate. The pulse-temperature ratio in mild 
cases is also a valuable aid. The pulse is practically always increased 
out of proportion to the temperature. The groins, axilla and anterior 
surfaces of clhows should be carefully examined for a punctate rash. 

97 



From morbilli, scarlatina is differentiated by its shorter prodro- 
mal period, the absence of coryza and conjunctivitis and especially 
by the absence of Koplik's spots. 

From rubella it is distinguished by the comparatively mild symp- 
toms of rubella, even with a widely distributed and well marked rash ; 
such a rash in scarlatina invariably causing a temperature of 102° 
to 103° F. 

The scarlatina type of rashes produced by belladonna, quinia and 
occasionally antipyrine are not associated with intense constitutional 
symptoms — the temperature is not much elevated if at all — and the 
scarlet angina is lacking. 

In erythema scarlatiniforme the fauces, though red, are not swol- 
len, the strawberry tongue is absent and the rash is frequently 
localized. Desquamation begins about the third or fourth day and 
is usually quite profuse while the rash is still present. 

Prognosis 

The "mortality of scarlatina varies in different epidemics; it is 
highest in children under five years of age. The general average of 
all ages is about twelve to fourteen per cent. 

In individual cases, even in the mild ones, a guarded prognosis 
must be given on account of the serious complications which may 
develop during the course of the disease. 

Treatment 

All cases, even the mildest, must be kept in bed for at least three 
weeks, and during this period the diet should consist entirely of milk. 
The temperature usually needs no special care, but if hyperpyrexia 
exists, hydrotherapy gives the best results. For the relief of the rest- 
lessness, an ice bag to the head and an occasional dose of phenacetin 
are usually satisfactory. 

The sore throat is frequently very annoying. Irrigations with hot 
normal salt solution or spraying with equal parts of hydrogen per- 
oxide and lime water affords considerable relief. An ice collar around 
the neck is often very agreeable to the patient. 

Careful watch must be kept upon the ears, as frequently an otitis 
or even mastoiditis may develop without being accompanied by pain. 
The drum membrane should be incised as soon as it is found to be 
congested and bulging. When the symptoms of mastoid involvement 
develop an early operation is advisable. 

The heart also must be watched carefully and as soon as the pulse 

98 



is rapid or irregular or the first sound of the heart is altered, stimu- 
lants should be used, such as digitalis, strophanthus, strychnia and 
whiskey. Whiskey is especially indicated in septic cases Avith severe 
angina and adenitis. The patient should be kept in bed until the pulse 
rate is practically normal. 

The urine should be examined frequently during the first three 
weeks. To prevent the development of nephritis the diet should be 
milk for at least three weeks; the patient should be encouraged to 
drink plenty of water — weak lemon or orangeades are very agree- 
able and can be allowed. The bowels should be kept open -wdth salines 
and an occasional dose of calomel or gray powder. If nephritis 
develops it should be treated as a nephritis from any other cause. 

As soon as desquamation begins, the patient should be given daily 
baths to assist the process. If oils are used they should not be 
carbolized, owing to the danger of absorption. 

Adenitis should be treated by ice bags or strong iehthyol oint- 
ments. As soon as pus is detected, it should be evacuated. 

For the arthritis immobilization of the affected joints, with aspirin 
or salicin internally. If pus forms, the joints must be freely opened. 
The treatment of this complication with a mixed streptococcus vac- 
cine has not been very satisfactory, but recently good results have 
been reported from the emploATnent of a serum prepared from dif- 
ferent strains of streptococci. 

The secondary anemia calls for tonics, especially iron and digi- 
talis. Basham's Mixture is a pleasant and efficient form of iron.

Erysipelas 

Synonym: St. Anthony's Fire 
Plate 55, Fig. 86 

Erysipelas is an acute inflammatory disease of the skin and 
sub-cutaneous tissues caused by the streptococcus (erysipelatous) 
pyogenes. After prodromal symptoms of from four to forty-eight 
hours' duration, consisting of malaise, chills, moderate fever and 
occasionally anorexia and vomiting, there appear at the site of 
infection one or more erythematous spots. These spots rapidly 
increase in size, forming a large, tense, red, shining patch, the tem- 
perature of which is higher than that of the normal skin. Its outline 
is usually irregular, but it is very sharply defined and its border is 
raised. Its size may be limited to a patch only a few inches in diam- 
eter, or it may involve large areas of the skin. As the process devel- 
ops the color becomes a dark, angry red, the swelling increases and 
vesicles and buUge, filled with a clear yellow serum, may develop. 
The amount of swelling depends on the intensity of the inflammatory 
process and on the structure of the subcutaneous tissues ; where there 
is much loose areolar tissue, it is often very considerable. 

Subjective symptoms are moderate pruritus, burning, tenderness 
and more or less pain. The rash reaches its height in about a week, 
remains stationary for a day or so and gradually subsides, together 
with a gradual improvement in the constitutional symptoms, which 
have consisted of those of an acute febrile disturbance from tox- 
aemia — temperature 103° to 105° F., headache, pain in the limbs, loss 
of appetite, coated tongue and nausea and vomiting, etc. 

The whole process may be very mild — the skin showing only an 
erythematous area with very little swelling and no vesicles or bullfp, 
accompanied by mild constitutional symptoms. Occasionally in 
severe cases the vesicles and bullae may be hemorrhagic. In some 
people who are peculiarly susceptible, erysipelas may recur fre- 
quently for a long period of time and by obstruction of the lymphatics

lead to elophantiasis. The hair is usually lost after erysipelas of the 
head and the alopecia resembles that of syphilis. 

Complications 

Secondary infection by staphylococci may cause extensive sup- 
purative cellulitis. Superficial abscesses occur frequently during 
convalescence. 

The most serious complications arise from the spreading of the 
disease to the mucous membrane of nose, mouth, pharjnix, larynx, 
rectum or vagina. 

Prognosis 

This should always be guarded. In extensive cases in the very 
young or in those debilitated by alcoholic excesses and exposure, the 
outlook is not favorable. A sudden rise of the temperature, after 
it has once subsided, means either another outbreak, or the develop- 
ment of a serious complication. 

Diagnosis 

An erythematous eczema is not accompanied by so much swelling, 
and never has the characteristic shining appearance of erysipelas. 
The line of demarcation between the affected and unaffected portions 
of the skin is usually ill defined in eczema. AVhen occurring upon the 
face, the scalp is usually spared, while an erysipelas tends to involve 
the scalp. 

Erysipeloid of Rosenhach, which as a rule occurs only on the 
fingers and hands, is characterized by much milder local reaction and 
the almost entire absence of constitutional symptoms. 

From the so-called pseudo-erysipelas that is secondary to intra- 
nasal inflammation erysipelas is distinguished by the severity of its 
constitutional symptoms, its tendency to spread widely beyond the 
nose and its adjacent tissues and the absence of history of a long 
continued nasal trouble. 

Angioneurotic edema does not present the glazed shiny surface of 
erysipelas and is not accompanied by symptoms of toxemia. It occurs 
in successive and recurrent attacks and is often accompanied by 
rheumatoid pains. 

Treatment 

Best in bed during the whole course of the disease. Isolation as 
in scarlatina or measles. The diet should be liquid and supporting. 

101 



Stimulants are frequently necessary. It has long been the custom to 
prescribe large and frequently repeated doses of the tincture of iron, 
but it is doubtful if this treatment is of much value. Quinia and 
antipyrine are sometimes of service in lowering the general tempera- 
ture. The treatment by antistreptococcus serums has not been very 
satisfactory in practice although theoretically it seemed quite prom- 
ising. The affected areas should be covered Avith wet dressings of 
alcohol, aluminum acetate, lead and opium wash, or ichthyol in a 
twenty to fifty per cent, aqueous solution. A favorite application 
formerly much used at the New York City Hospital was the saturated 
solution of magnesium sulphate. Sdbouraud} recommends colloidal 
silver as a local application.

Exfoliatio Areata Linguae 

Synonyms: Pityriasis linguae, Transitory bonign plaques of the tongue. 

Geographical tongue. 

Plate 56, Fig. 87 

This affection is a peculiar arrangement of the normal coating of 
the tongue which has received various designations and has been 
explained in many ways. It has been looked upon in some quarters as 
a glossitis, even of an ulcerated kind ; in others as a simple desquama- 
tion or exfoliation. It has been regarded as a manifestation of syph- 
ilis. Since it has been seen in nurslings, several causal factors are 
thereby eliminated, as for example dependence on dentition. 

The pediatrist Czerny has perhaps thrown some light upon the 
condition by making it an expression of the exudative diathesis. This 
makes it hereditary, at least in its predisposition. It may also be 
looked upon as a permanent peculiarity dependent for its manifesta- 
tions on accidents — dietetic peculiarities. It often improves under a 
strict, bland diet. The geographical tongue, in other words, is made 
much worse by the same dietetic factors which cause acute indigestion 
and diarrhea. But aside from the exudative diathesis and improper 
or excessive eating, numerous other factors may be isolated, as 
neuropathy, climate, mechanical irritation. 

The appearance of a geographical tongue is quite characteristic. 
The tongue is the seat of plaques of a lively red color, varying much 
in size and shape. They are chiefly rounded, however, and very 
slightly prominent. The papillae in these areas appear enlarged. At 
the border of the plaques is a narrow, gray, stippled areola. In some 
instances the border has a distinct double contour. The stippling is 
simply the filiform papillae, rendered conspicuous because broadened 
and surmounted by thickened epidermis. These papillae are also uni- 
formly enlarged in other parts of the tongue, which present thereby 
a grain leather appearance. Although the condition is spoken of as 
a permanent one, individual plaques show great volatility. Even be- 

108 



fore the end of tliirty-six hours they may have run through their cycle 
and vanished, as new plaques appear. The process has therefore 
been likened to the alteration of patterns in a kaleidoscope. 

Diagnosis 

The affection has no doubt been confounded with Mdller's glos- 
sitis and mucous patches of syphilis. The greatest confusion would 
be likely to arise if some other affection acted as an exciting cause to 
geographical tongue — syphilis, for example. 

Treatment 

There is no treatment to be actually directed against this condi- 
tion per se. The individual may be treated to restore him to physio- 
logic equilibrium, and the various local applications used in mild 
stomatitis seem to be indicated on general principles.

Leukoplakia 

Plate 56, Fig. 88 

Clmieally, leukoplakia is represented by smooth, milk-wliite spots 
which at first are of a pale rose tint and not well differentiated from 
the outlying mucosa. They become pure white, and sometimes even- 
tually bluish or pearly. Eventually they become shariily differen- 
tiated at the borders, the more so because often surrounded by a 
bright-red areola. The thickened epidermis, becoming harder with 
time, is eventually detached, and when they come away leave a shal- 
low or deep fissure. That an ulcer does not develop is due to the 
peculiar narrow shape of the original lesion. The white color may 
become dark — yellowish or brownish — from minute hemorrhages. 
Some of the lesions have almost a cartilaginous hardness and thick- 
ness. The mucous membrane beneath these thickenings is rich in 
blood-vessels, which are permeated with leucocytes. The papilla are 
elongated and increased in number. 

In a tjT)ical case we encounter a number of lesions on the anterior 
portion of the dorsum of the tongue ; and if the case is chronic we may 
see side by side spots in all stages of development with fissures left 
by former spots. The tip and borders are involved in the affected 
area. The most favorite locality is the inner aspect of the cheeks. 
where a triangular area is implicated. Fissures seem to be almost 
peculiar to the tongue. 

An extraordinary feature, when we bear in mind the amount of 
discomfort caused by various kinds of sore mouth, is the relative 
absence of subjective symptoms in a large percentage of cases. It 
often happens that the presence of leukoplakia is discovered by mere 
accident. The subjective sensations may consist of nothing beyond a 
numb or foreign body sensation — the latter due in part to the thick- 
ened areas in the act of separation. 

Etiology 

The affection is extremely chronic and confined almost entirely 
to males, who are seldom attacked before the age of forty. It ap- 

105 



pears to result from the cooperation of a number of causes. The 
most common association is antecedent syphilis and tobacco-smoking, 
but these only furnish a predisposition. 

Diagnosis 

There is a notable resemblance to the mucous patches of syphilis, 
which are first white and then succeeded by raw surfaces. As a rule, 
leukoplakia spots are much more numerous and prominent. Mucous 
patches are usually seen at the sides, tip and under surface of the 
tongue. They come and go within a short interval, while leukoplakia 
is extremely chronic, lasting for years, and having little tendency to 
recovery. The fissures which result might be confused with later 
syphilitic disease. The crucial test is the result of treatment, which 
is principally negative in leukoplakia. 

Prognosis 

This is not particularly good for recovery and the affection must 
be looked upon as a serious one when we consider that it is a not un- 
common forerunner of cancer. 

Treatment 

All sources of irritation must be removed. Sharp teeth which rub 
against lesions should be filed do\\Ti and all carious teeth either filled 
or extracted. Tobacco and all pungent food articles and the taking 
of hot foods and drinks must be proscribed. For inveterate smokers 
a very moderate indulgence may be permitted. Mouth washes must 
be used freely and may be alternated. Hydrogen peroxide seems to be 
the best suited, an(^ any mild astringent solution may be employed. 
For actual treatment to produce permanent results various mild caus- 
tics are used, the strength to be gradually increased. The very 
number of these in use goes to show the lack of a dependable remedy 
— silver nitrate, chromic acid, lactic acid, salicylic acid, etc., etc. 
Occasionally cases are benefited by injections of salvarsan. Some 
surgeons recommend the removal of the entire epithelial coating with 
curette or cautery, but it is not certain that the results warrant such 
measures.
