[Prostatic leiomyosarcoma].

The histopathological findings from the third prostate operation of a 63-year-old patient proved that his leiomysarcoma was malignant. Leiomyosarcoma is a disease of low incidence. Of 1000 cases of a carcinoma of prostate one proves to be this disease. Its clinical distinction from benign prostate disease meets difficulties. A survey of literature has shown that even multiple aggressive therapy fails when the process has overpassed the limits of the organ. Early diagnosis followed be radical pre- and postoperative X-irradiation may lead to long-term survival. Neither cytostatic nor hormonal therapy is successful. The course of the illness of our patients merits interest because of the rarity of the disease and the diagnostic difficulties.
