Persons subject to atopic eczema may present a varioliform eruption as a complication. Kaposi1recognized this fact, describing the eruption in 1887. Juliusberg2also recorded the condition, under the title of pustulosis acuta varioliformis. Both terms suggest a kinship to the eruptive virus diseases, and the presence of the umbilicated pustules certainly adds weight to the possibility of this relationship. The appearance of the firm umbilicated pustule with the dry adherent serosanguineous crust in the umbilication is distinctive; once seen the eruption is not readily confused with those of ordinary pustular dermatoses. The pustules are discrete, and peripheral extension, as encountered in the impetiginous processes, is seldom found. Few of the case reports noted any tendency toward grouping of the lesions, and the eruption was localized most often on the face and neck. The inflammatory reaction is severe; regional adenopathy is the rule, and the systemic phase, indicated
