Successful association in the treatment of pityriasis lichenoides et varioliformis acuta.

摘要

Pityriasis lichenoides (PL) is an uncommon inflammatory skin disease. Traditionally, two clinical forms can be distinguished: pityriasis lichenoides et varioliformis acuta (PLEVA) and pityriasis lichenoides chronica (PLC). PLEVA is characterized by a generalized eruption of acute onset, consisting of papular lesions that develop central necrosis and scar. In contrast, PLC is typified by small scaly red papules that do not evolve into necrotic lesions and may persist for months or years. PLEVA and PLC represent two variants of the clinical and histological spectrum of PL, but intermediate forms can occur, especially in children.
