title: Lymphoepithelioma-like carcinoma of the ureter: a rare presentation, synchronous with conventional urothelial carcinoma.
abstract: 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.
