[Leiomyosarcoma of the prostate. Report of a case]

Sarcomas of the prostate are rare tumors and are predominantly rhabdomyosarcoma in children and leiomyosarcoma in the young adult (less than 50 years). We report on a rare case of prostate sarcoma in a 49-year-old patient whose presenting features were those of rapidly evolving prostatism and dyschezia (rectal constipation). The diagnosis was established histopathologically by cytology and biopsy. Despite the initial chemotherapeutic treatment, the course of the disease was fulminant and the patient died from multiple lymphatic metastases. We discuss its embryonal origin, clinical features, differential diagnosis and underscore the need for sequential combined treatment with chemotherapy, surgery and post-operative radiotherapy.
