Abstract:
Urinary bladder leiomyosarcoma is an extremely rare malignancy of the urogenital system. We present the case of a 59-year-old Caucasian male with a gigantic bladder leiomyosarcoma. The patient was subdued to the surgical excision of the urinary bladder - laparoscopic radical cystectomy with extended pelvic lymphadenectomy, with urinary diversion by bilateral ureterocutaneostomy. The excision was complete both macroscopically and microscopically. No additional adjuvant therapy was administered. In the 6-month follow-up, the patient remained in radiological remission. Surgical excision with extended pelvic lymphadenectomy seems to be sufficient in the treatment of urinary bladder leiomyosarcoma.
