Le léiomyosarcome de la vessie: à propos de 3 cas

Bladder leiomyosarcoma is a rare highly malignant tumor. It can occur in children and adults with a maximum incidence in patients over 60 years of age. It mainly affects men, with a sex ratio of 3/1. Its clinical features are non-specific and dominated by the haematuria. Endoscopic resection of the bladder associated with anatomo-pathological examination allow the diagnosis. Its treatment remains controversial due to the rarity of cases reported in the literature. Neoadjuvant chemotherapy followed by radical cystectomy is the treatment of choice, if the patient's clinical condition permit. We report 3 cases of bladder leiomyosarcoma treated by radical cystectomy and with uneventful postoperative course.
