Total endoscopic management of a patient with urinary bladder leiomyosarcoma presenting with dysuria: A case report

The pathophysiology of bladder leiomyosarcoma, a rare disease with aggressive mesenchymal tumor, is not certain, but its main symptoms are hematuria, dysuria and abdominal pain. Cases described in the literature are few. This report describes a case of a leiomyosarcoma of the urinary bladder in a 49-year-old woman. After CT scanning revealed a heterogeneously enhanced 4-cm mass involving the bladder neck and anterior wall, further examinations detected no metastatic lesion. Cystoscopy and transurethral resection of bladder tumor (TURBT) were performed. The histopathological diagnosis was leiomyosarcoma. Postoperative period was uneventful. The patient experienced complete resolution of urologic symptoms. Repeat-TURBT was performed 70 days after first surgery. The patient has remained disease-free 18 months after surgery.
