Abstract

Pityriasis lichenoides et varioliformis acuta and pityriasis lichenoides chronica represent 2 ends of a disease spectrum of unknown etiology. Herein we describe 2 cases of pityriasis lichenoides et varioliformis acuta, in which human herpesvirus 7 DNA was detected in skin samples by polymerase chain reaction methodology, an association not previously described. This report may support the involvement of viral infection in the etiopathogeny of this disease.

Keywords: Etiology; Etiología; PLEVA; VHH7.
