Lymphoepithelioma-like carcinoma (LELC) is a rare finding in the upper urinary tract. The presenting clinical findings mimic those of other more common upper-tract tumors, such as urothelial carcinoma. Preoperative imaging has not been shown to reliably predict the diagnosis of LELC. This tumor can be misdiagnosed as a reactive inflammatory lesion or lymphoma if the proper immunohistochemical stains for cytokeratin are not used.
淋巴上皮瘤样癌（LELC）在上尿路中较为罕见。其临床表现与其他更常见的上尿路肿瘤相似，如尿路上皮癌。术前影像学检查尚未被证明能可靠地预测LELC的诊断。如果未使用合适的细胞角蛋白免疫组化染色，这种肿瘤可能会被误诊为反应性炎性病变或淋巴瘤。
