A 47-year-old man presented with an inverted papillary carcinoma of the urinary bladder. Cystoscopy revealed an approximately 2 cm mass, with a small stalk and smooth surface, which was situated just medial to the right ureteral orifice. Transurethral resection of the tumor was performed on July 25, 1983. Malignant changes were recognized in the epithelial cords in the resected specimen. This is in contrast to the general view that inverted papilloma of the urinary bladder is benign in nature. The authors believe that careful pathologic examination should be done when an inverted type tumor of the urinary tracts is found. No recurrence has been recognized as of September 11, 1987.
一名47岁男性被诊断为膀胱内翻性乳头状癌。膀胱镜检查发现一个约2厘米大小的肿物，有一小蒂且表面光滑，位于右输尿管口内侧。1983年7月25日进行了经尿道肿瘤切除术。在切除标本的上皮条索中发现了恶性改变。这与膀胱内翻性乳头状瘤本质上为良性的普遍观点相悖。作者认为，当发现尿路出现内翻型肿瘤时，应进行仔细的病理检查。截至1987年9月11日，未见复发。
