Abstract


Non-urothelial neoplasms of the bladder account for less than 5% of all bladder tumors. Leiomyosarcoma is the most common malignant mesenchymal tumor that arises in the adult bladder. Leiomyosarcomas of the bladder are considered to be highly aggressive tumors. Most patients present at an advanced stage, with less than 30% of patients presenting with stage T1 disease. Surgical resection still remains the cornerstone of treatment with the status of the surgical margin being a strong predictor of the outcome. A 59-year-old man presented to our institution with urinary urgency, and cystoscopic examination revealed a huge submucosal mass on the lateral bladder wall. A radical cystoprostatectomy and ileal neobladder procedure was performed. The patient was diagnosed with a primary leiomyosarcoma of the bladder. After 1 year of follow-up, there has been no recurrence or metastasis.
