Villous adenomas are common lesions of the gastrointestinal tract but they are rarely located in the urinary tract including the urinary bladder. There are a few case reports and series in the literature. Here we report a 43-year-old male patient who had a polypoid lesion located on the left lateral wall of the urinary bladder. Transurethral resection was performed. The diagnosis was 'villous adenoma of urinary bladder' with clinical and histopathological findings. Villous adenomas are mostly seen in elderly males. The coexistence of villous adenoma with adenocarcinoma, squamous cell carcinoma, and urothelial carcinoma was observed but there is not clear evidence about progression to carcinoma, in spite of its colonic counterpart. Generally complete surgical resection is accepted as curative but there are no exact data about follow-up and recurrence. By presenting this case, we aim to emphasize that it is a rare but important lesion because of coexistence with malignancies and uncertain malignant potential.
绒毛状腺瘤是胃肠道的常见病变，但很少位于包括膀胱在内的泌尿道。文献中有一些病例报告和系列研究。在此，我们报告一名43岁男性患者，其膀胱左侧壁有一个息肉样病变。进行了经尿道切除术。根据临床和组织病理学检查结果，诊断为“膀胱绒毛状腺瘤”。绒毛状腺瘤多见于老年男性。虽然观察到绒毛状腺瘤与腺癌、鳞状细胞癌和尿路上皮癌共存，但尽管其结肠对应物有恶变情况，但关于其进展为癌尚无明确证据。一般认为完整的手术切除是治愈性的，但关于随访和复发尚无确切数据。通过展示该病例，我们旨在强调它是一种罕见但重要的病变，因为它与恶性肿瘤共存且恶性潜能不确定。
