Excerpt from The Journal of Cutaneous Diseases, Including Syphilis, Vol. 36: Official Organ of the American Dermatological Association; December, 1918 As nearly all toxic erythemas show a close resemblance to each other and their symptoms do not offer any possibility of classification (except a few), the rational method is followed by dividing them according to their etiology. And thus two large groups will be dis cussed: (1) that in which the causative agents are substances ingested as food or certain chemical material formed within the body, and (2) the erythemas following the administration of drugs. To these will be added a brief consideration of urticaria, which is truly a toxic erythema, and Of the serotherapeutic erythemas.
