In the present report, we describe a patient with microcystic variant of urothelial carcinoma in urinary bladder. In March 2016, a 71-year-old man presented with bladder tumors found incidentally by ultrasonography. Cystoscopy and contrast-enhanced computed tomography (CT) revealed multiple invasive tumor of posterior wall, with a maximum diameter of 33 mm. Transurethral resection (TUR) of bladder tumors was performed. Pathological diagnosis was urothelial carcinoma, high grade, T2 or more. Invasive urothelial carcinoma was diagnosed and laparoscopic radical cystectomy with orthotopic neobladder was performed accordingly in April 2016. Pathological findings indicated a diagnosis of microcystic variant of urothelial carcinoma. At present, six months after surgery, the patient remains free of recurrence and metastasis. Here we review the characteristics of 4 microcystic variant of urothelial carcinoma cases reported in Japan.
在本报告中，我们描述了一名患有膀胱尿路上皮癌微囊性变体的患者。2016年3月，一名71岁男性因超声检查偶然发现膀胱肿瘤。膀胱镜检查和增强计算机断层扫描（CT）显示后壁有多个浸润性肿瘤，最大直径为33毫米。进行了经尿道膀胱肿瘤切除术（TUR）。病理诊断为尿路上皮癌，高级别，T2期或更高。诊断为浸润性尿路上皮癌，并于2016年4月相应地进行了腹腔镜根治性膀胱切除术并原位新膀胱术。病理结果表明诊断为尿路上皮癌微囊性变体。目前，术后六个月，患者仍无复发和转移。在此我们回顾了日本报道的4例尿路上皮癌微囊性变体病例的特征。
