[Kaposi's sarcoma of the urinary bladder after kidney transplantation].

In 1872 the Viennese dermatologist Moritz Kaposi first described a pigment sarcoma of the skin. A modification of the epidemiology and the follow-up results in the accumulation of reports about the Kaposi-sarcoma after organ transplantation in the sixties and in the beginning of the eighties frequently Kaposi-sarcomas by the immunodefect syndrome AIDS were noticed. The incidence of Kaposi-sarcomas after kidney transplantations is estimated to be 0.3 to 1.8 per thousand. We report about a patient developing a Kaposi-sarcoma of the bladder during an immunosuppression therapy with Imurec and Sandimmun.
