[Leiomyosarcoma of the prostate accompanied by multiple hepatocellular carcinoma: report of a case]

A case of leiomyosarcoma of the prostate accompanied by multiple hepatocellular carcinoma in a 51-year-old man is presented. He visited our hospital with the complaints of feeling of residual urine and pain of the coccygeal bone in November, 1990. A histopathological study of the transrectal needle biopsy specimens revealed leiomyosarcoma of the prostate. Since multiple liver tumors were pointed out, the patient was given combined chemotherapy (CYVADIC: cyclophosphamide, vincristine, adriamycin and DTIC). He died 1 year and 2 months after the initial diagnosis due to hepatic failure. The autopsy findings revealed that the histology of the liver tumors was hepatocellular carcinoma, and that the leiomyosarcoma of the prostate had directly invaded the wall of the urinary bladder and the rectum, but there was no obvious distant metastasis.
