PITYRIASIS ROSEA: Report of Three Cases in One Family, with Clinical Variations in Two of Them

Arch Derm Syphilol. 1941;44(1):66-68. doi:10.1001/archderm.1941.01500010069013
Abstract

The infectious transmission of pityriasis rosea is still an open question. The incidence of the occurrence of 2 or more cases in the same household is small compared with the total number of cases which have been reported. Niles and Klumpp1 in a comprehensive review of the literature cited 35 cases. Of these, 15 were reported by different observers, while 20 were observed by Butterworth.2 In their own series of 219 cases no 2 patients were members of the same household. Swartz3 reported the disease in 3 members of his own family. It may be that occurrences of this kind are more frequent than the literature would indicate.

The present report of 3 cases of pityriasis rosea in members of the same family is made because of the apparent rarity of such occurrences and because of the atypical clinical picture in 2 of them.
