Lymphoepithelioma-like carcinoma is an undifferentiated epithelial tumor with a prominent lymphocytic infiltrate and is rarely seen in the upper urinary tract. Only 3 and 2 cases involving the ureter and renal pelvis, respectively, have been reported. We report the fourth documented case of lymphoepithelioma-like carcinoma of the ureter. Tumor cells were immunoreactive to cytokeratin and negative for Epstein-Barr virus. Our patient was disease free 30 months after nephroureterectomy. The prognosis is favorable for pure lymphoepithelioma-like carcinoma of the upper urinary tract.
淋巴上皮瘤样癌是一种未分化上皮性肿瘤，伴有显著的淋巴细胞浸润，在上尿路中罕见。分别仅有3例和2例累及输尿管和肾盂的病例报道。我们报告第四例有文献记载的输尿管淋巴上皮瘤样癌病例。肿瘤细胞对细胞角蛋白呈免疫反应性，对爱泼斯坦-巴尔病毒呈阴性。我们的患者在肾输尿管切除术后30个月无疾病。上尿路纯淋巴上皮瘤样癌的预后良好。
