Kaposi's sarcoma presenting as autoimmune hemolytic anemia.

A case of Kaposi's sarcoma which presented as a warm type of immune hemolytic anemia is described. The malignancy was discovered at the time of splenectomy, which was required for control of the hemolytic anemia. Three other cases of immune hemolytic anemia in patients with Kaposi's sarcoma have been reported. An association between Kaposi's sarcoma and immune hemolytic anemia is suggested. Careful examination of the skin for Kaposi's sarcoma seems appropriate in cases of immune hemolytic anemia.
