We report two cases of clear cell adenocarcinoma arising in the urethral diverticulum. Case 1 occurred in a 79-year-old woman presenting with complaints of frequent micturition. Magnetic resonance imaging (MRI) revealed a localized urethral diverticular tumor. Transurethral resection of the tumor was performed, and the final histopathological diagnosis was clear cell adenocarcinoma. Anterior pelvic exenteration was performed. She had no recurrence 15 months after surgery. Case 2 occurred in a 79-year-old woman presenting with urinary incontinence. As in Case 1, MRI and histopathological findings of transurethral resection of the tumor revealed clear cell adenocarcinoma in the urethral diverticulum. Anterior pelvic exenteration and ileal conduit formation were performed. She had no recurrence 16 months after surgery. Clear cell adenocarcinoma in the urethral diverticulum is very rare. We review 17 cases of clear cell adenocarcinoma arising in the urethral diverticulum in Japan.
我们报告了两例发生于尿道憩室的透明细胞腺癌病例。病例1发生在一名79岁女性身上，她主诉尿频。磁共振成像（MRI）显示为局限性尿道憩室肿瘤。进行了经尿道肿瘤切除术，最终组织病理学诊断为透明细胞腺癌。实施了前盆腔脏器清除术。术后15个月她未复发。病例2发生在一名79岁女性身上，她表现为尿失禁。与病例1一样，肿瘤经尿道切除后的MRI和组织病理学检查结果显示尿道憩室内为透明细胞腺癌。实施了前盆腔脏器清除术和回肠代膀胱术。术后16个月她未复发。尿道憩室内的透明细胞腺癌非常罕见。我们回顾了日本17例发生于尿道憩室的透明细胞腺癌病例。
