ORIGINAL ARTICLES. disease portraying the more important varieties of the process have been reported during the past year,1 it will not be necessary to reconsider the disease on the present occasion beyond pointing out the principal features of the two varieties which concern this paper, namely, the vesicular and bullous. The following is an abstract of the original description of the ves- icular variety. RELATION OF HERPES GESTATIONIS AND CERTAIN OTHER FORMS OF DISEASE TO DERMATITIS HERPETIFORMIS.1 PROFESSOR OF SKIN DISEASES IN THE UNIVERSITY OF PENNSYLVANIA. By LOUIS A. DU PI RING, M.D., In my original communication on Dermatitis Her- petiformis, read before the American Medical Asso- ciation,2 that disease was described, and its symp- toms and several varieties given. It was there stated that the pustular variety is the same manifestation as the affection described by Hebra as “ impetigo her- petiformis.” This latter subject has more recently been elaborated by me in a paper read before this Association3 at its last meeting. On the same occasion I presented a “ Preliminary Note on the Relation of Dermatitis Herpetiformis to Herpes Gestationis and Other Similar Forms of Dis- ease,”1 which communication embodied the results of considerable research into literature bearing upon the subject. It was there stated, as had been inti- mated in my previous articles, that so-called herpes gestationis, as well as certain other similar forms of eruption, reported with various titles, are all in- stances ot one process, namely, dermatitis herpeti- formis, as I had defined this disease. It is characterized by variously sized, varying from a pin-head to a pea, flat or raised, irregularly shaped or stellate, glistening, pale-yellowish or pearly, usually firm or tensely distended vesicles, as a rule, unaccompanied by areolae. In their early stages they can be seen only with difficulty, and are liable to be overlooked in the examination. Sometimes they can only be detected or seen to advantage in an oblique light In size they vary extremely, large and small being formed side by side, and in this respect they differ from the vesicles of ec- zema. Here and there papules, papulo-vesicles, vesico- pustules, and small blebs will sometimes be encountered. The eruption as a whole is disseminate, the lesions ex- isting scattered more or less profusely over a given region, as, for example, the neck or the back, but they are for the most part aggregated in the form of small clusters or groups of two, three or more; or there may be patches here and there as large as a silver dollar, upon which a number will be seated. When in close proximity they incline to coalesce, as in herpes zoster, forming multilocular vesicles or small blebs. Where this occurs they are generally slightly raised and are surrounded with a pale or reddish areola, which shows forth the irregular, angular or stellate outline of the lesion. At this stage, moreover, the little cluster will generally present a “puckered” or “drawn up” ap- pearance, indicative of its herpetic nature. The erup- tion is usually profuse, sometimes to the extent of the upper extremities, trunk and thighs being well covered. It may attack any region, but the neck, chest, back, abdomen, upper extremities and thighs are especially liable to invasion. The remarks about to be made must be regarded as supplementary to the preliminary note referred to, since presenting which I have been able to investi- gate further and collate the notes of some of these cases, which I desire now to bring forward in sub- stantiation of my statement. It will be observed that the clinical features of the cases bear a strong resemblance to one another. It will not be neces- sary, however, for my purpose to quote all the cases in extenso. The most striking symptom is the itching. Not in- frequently burning is also complained of. Itching, however, predominates, and is violent or intense. It is altogether disproportionately in excess of the amount of eruption. It is, moreover, a persistent itching, caus- ing the sufferer to scratch constantly. It generally pre- cedes the outbreak, and does not abate until the lesions have been ruptured. From my observation I should say that it is usually more severe and more lasting than The object of this communication will be to show: 1. The identity of so-called herpes gestationis with the vesicular variety of dermatitis herpetiformis. 2. That certain other forms of so-called herpes re- ported with various titles are likewise manifestations of the same variety of this disease. 3. That certain cases reported as “ peculiar forms of pemphigus ’ ’ must also be viewed as examples of the vesicular or bullous varieties of this disease. 1 Notes of a Case of Dermatitis Herpetiformis Extending over Eleven Years, Illustrating the Several Varieties of the Disease.
