[Primary leiomyosarcoma of the epididymis: a case report with review of the literature].

Primary epididymal leiomyosarcoma is uncommon: only 16 cases has been reported in the literature. We present an additionnal case in a 78-year-old man, treated for a prostatic adenocarcinoma by gonadorelin (LH-RH) analogue, who had an epididymal tumor. A right orchidectomy with high ligation of the spermatic cord was performed. The diagnostic of primary leiomyosarcoma of the epididymis was made. The patient is dead 2 years later with no recurrence of disease. A review of reported cases is made.
