Abstract:
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.

Because of the thinness of the cells, simple squamous epithelium is present where the rapid passage of chemical compounds is observed. For example, the endothelium that lines the capillaries and vessels...
