Malignant proliferating angioendotheliomatosis.

A 48-year-old man had fever and generalized asymptomatic erythematous telangiectatic plaques and patches. Skin biopsy specimens confirmed the diagnosis of malignant angioendotheliomatosis. Local irradiation therapy induced a temporary remission. Chemotherapy was administered without altering the course of the disorder. Limited autopsy revealed visceral as well as cutaneous involvement.
