[Leiomyosarcoma of the prostate: a case report].

A 39-year-old man with the chief complaints of gross hematuria and dysuria was referred to our hospital on June 6th, 1985. Physical examination revealed a tumor in the left lobe of the prostate. Prostatic needle biopsy showed the histological evidence of leiomyosarcoma. Pelvic exenteration with pelvic lymph adenectomy was performed on June 18th, 1985. Histological findings of the tumor revealed leiomyosarcoma and no lymph nodes metastasis. Two courses of vincristine-adriamycin-cyclophosphamide chemotherapy were given postoperatively after a clonogenic assay was done. He considerably improved and was discharged 3 months after operation. He shows no recurrence of tumor 17 months after operation. Thirty-three cases of leiomyosarcoma reported in Japan are reviewed.
