title: [Prostatic leiomyosarcoma. Report of a case a review of the literature].
abstract: A 48-year-old male with a leiomyosarcoma of the prostate is presented. The clinical presenting features were those of rapidly evolving prostatism and rectal symptoms (rectal bleeding, sense of rectal fullness and perineal pain). Arising from the smooth muscle cells of the prostate gland, this is a rare neoplasm that account for less than 0.1% of prostate malignancies, with a poor prognosis. It is often difficult to determine a definite origin, being necessary the differential diagnosis with pseudosarcoma, inflammatory fibrosarcoma, prostate abscess and other rare tumors. There is no established protocol of treatment. Combined modality therapy including radical surgery, radiation therapy and chemotherapy seems to be the best, although prognosis remains poor.
