ARIAS RODRIGUEZ, C.  e  HOYOS MONROY, Deissy C.. Acute varioliform lichenoid pityriasis following the initiation of erythropoietin. Rev. argent. dermatol. [online]. 2023, vol.104, pp.31-40. ISSN 1851-300X.

Pityriasis lichenoides et varioliformes acuta (PLEVA) is part of a group of diseases clustered as pityriasis lichenoides, next to febrile ulceronecrotic Mucha-Habermann disease and pityriasis lichenoides chronica. It’s characterized by a sudden onset of multiple erythematous and violaceous papules which develop necrosis, leaving residual dyschromia and varioliform scars. It’s been hypothesized the possible role of infectious agents, lymphoproliferative diseases, immune complexes and drugs. We present the case of a woman with a typical PLEVA with histopathological confirmation, whose lesions appeared after therapy with erythropoietin.
