Pityriasis lichenoides et varioliformis acuta (Habermann) or parapsoriasis varioliformis (Wise) is a rare disease, first described by Mucha1 of Vienna in 1916. This disease entity is characterized by a polymorphous and polychromatic eruption with four types of lesions: papules, scaly lesions not unlike pityriasis rosea, necrotic or hemorrhagic vesicles closely simulating varicella and depressed scars. The cutaneous manifestations are usually unaccompanied by constitutional or local symptoms and persist for from one month to two years.
The first case in the American literature was reported by Wise and Sulzberger,2 in October 1930. Senear and Oliver3 had previously reported three cases at the June 1930 meeting of the American Dermatological Society, but the reports did not appear in print until January 1931.
Since Mucha's first description of the disease, about sixty-four cases have been reported in the world literature. Gougerot and Burnier4 reported a case and listed fifty-two
