Lymphoepithelioma-like carcinoma (LELC) in the bladder is uncommon with a reported incidence of 0.4%-1.3% of all bladder carcinomas. In Japan, some occurrences of LELC have been reported in the renal pelvis and ureter but only two in the bladder. A bladder tumor was identified in a 70-year-old man suffering from macroscopic hematuria for 2 months. Sections of the transurethral tumor resection showed invasive high-grade urothelial carcinoma. The patient was diagnosed with local invasive bladder tumor, and cystectomy with ileal conduit formation was performed. The final pathological evaluation was predominant LELC with urothelial carcinoma. We present a new case of LELC in the bladder and performed a review of all published cases of LELC in the urinary tract to obtain its characteristics and prognostic guide.
膀胱淋巴上皮瘤样癌（LELC）并不常见，据报道其发病率占所有膀胱癌的0.4%-1.3%。在日本，肾盂和输尿管有一些LELC病例的报道，但膀胱仅有两例。一名70岁男性因肉眼血尿2个月被发现患有膀胱肿瘤。经尿道肿瘤切除标本切片显示为浸润性高级别尿路上皮癌。该患者被诊断为局部浸润性膀胱肿瘤，并进行了膀胱切除术及回肠代膀胱术。最终病理评估为以LELC为主伴尿路上皮癌。我们报告一例新的膀胱LELC病例，并对所有已发表的尿路LELC病例进行回顾，以了解其特征和预后指导。
