[Auto-immune hemolytic anemia associated with Kaposi's sarcoma. Report of a new case (author's transl)]

The association of Kaposi angiosarcomatosis and an auto-immune haemolytic anaemia is reported in a 69-year-old woman. The direct Coombs test was "igG complement" type positive. This is the 5th reported case and the 2nd in which haemolysis developed during an acute malignant exacerbation of the disease. The patient died less than 4 months following the diagnosis of Kaposi's sarcoma, after treatment with prednisone and chlorambucil. Lymphoid and immunological abnormalities are not rare during the course of Kaposi's sarcoma. The reasons are discussed briefly.
