A unique case of transitional cell carcinoma of the bladder with the primary being in the anus is reported. The patient presented with acute urinary retention from a large bladder tumor, which was thought to be primary to the bladder. Biopsy of the bladder revealed transitional cell carcinoma, microscopically indistinguishable from the primary cloacogenic carcinoma diagnosed seven years previously.
报告了一例罕见的膀胱移行细胞癌病例，原发灶位于肛门。患者因巨大膀胱肿瘤导致急性尿潴留就诊，最初认为肿瘤原发于膀胱。膀胱活检显示为移行细胞癌，显微镜下与七年前诊断的原发性泄殖腔源癌无法区分。
