[Kaposi's sarcoma and aplastic pancytopenia: simultaneous occurrence in a patient]

A 49 year old patient developed simultaneously a histologically verified Kaposi's sarcoma and an idiopathic aplastic pancytopenia. An association of these perhaps virus-induced diseases has not been reported until now. Consequences concerning the diagnostic approach of changes in peripheral blood cells in patients with Kaposi's sarcoma are delineated. Changes in peripheral blood and bone marrow in patients with Kaposi's sarcoma are discussed.
