Pityriasis lichenoides et varioliformis acuta (PLEVA) is an uncommon skin disorder, clinically characterized by an acute onset of a polymorphic eruption. The disease has an unpredictable course, the pathogenesis is not fully understood, and many treatments have been proposed while self-resolution may occur. Hence, We report a puzzling case of PLEVA in its early stage of transition to a febrile ulceronecrotic Mucha-Habermann disease.
