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.
膀胱平滑肌肉瘤是一种罕见的侵袭性间叶肿瘤,其病理生理学尚不确定,但其主要症状为血尿、排尿困难和腹痛。文献中描述的病例很少。本报告描述了一名49岁女性膀胱平滑肌肉瘤的病例。CT扫描显示一个4厘米大小、不均匀强化的肿块,累及膀胱颈和前壁,进一步检查未发现转移病灶。进行了膀胱镜检查和经尿道膀胱肿瘤切除术(TURBT)。组织病理学诊断为平滑肌肉瘤。术后恢复顺利。患者的泌尿系统症状完全消失。首次手术后70天进行了再次TURBT。患者术后18个月无疾病复发。
