A case of vesico-appendiceal fistula caused by appendiceal cancer is reported. A 37-year-old male was admitted with the chief complaint of suspended dust in the urine. Under cystoscopy, a tumor (1 cm diameter) was found in the right posterior wall of the bladder. Transurethral resection of the bladder tumor was performed. The pathological outcome was intestinal metaplasia without malignancy. Preoperative abdominal computed tomography suggested vesico-appendiceal fistula, retrospectively. Therefore, appendectomy with partial cystectomy was attempted. However, the appendix was adhered to the sigmoid mesocolon, therefore, appendectomy, partial cystectomy, and sigmoid colectomy were performed. We diagnosed the tumor as mucinous adenocarcinoma. The patient has been receiving adjuvant chemotherapy with tegafur-gimeracil-oteracil potassium for 17 months, because he refused right hemicolectomy. There was no evidence of recurrence after 58 months of follow-up. Vesico-appendiceal fistula caused by appendiceal cancer is very rare. Our case is the 21st case reported in Japan.
报告了一例由阑尾癌引起的膀胱-阑尾瘘病例。一名37岁男性因主诉尿液中有悬浮物入院。膀胱镜检查发现膀胱右后壁有一个肿瘤（直径1厘米）。进行了经尿道膀胱肿瘤切除术。病理结果为无恶性的肠化生。回顾性分析术前腹部计算机断层扫描提示膀胱-阑尾瘘。因此，尝试进行阑尾切除术加部分膀胱切除术。然而，阑尾与乙状结肠系膜粘连，因此，进行了阑尾切除术、部分膀胱切除术和乙状结肠切除术。我们将肿瘤诊断为黏液腺癌。由于患者拒绝右半结肠切除术，一直在接受替吉奥辅助化疗17个月。随访58个月后无复发迹象。由阑尾癌引起的膀胱-阑尾瘘非常罕见。我们的病例是日本报告的第21例。
