Lymphoepithelioma-like carcinoma (LELC) is best known to occur in the nasopharynx. When LELC occurs in the urinary tract, this extremely rare neoplasm most commonly affects the bladder but has also been reported in the renal pelvis, ureter, prostate, and urethra.
We present a case of LELC arising in the right renal pelvis of a 73-year-old woman with hematuria and hydronephrosis. Computed tomography demonstrated right renal pelvis tumor. Ureteroscopy biopsy showed papillary urothelial neoplasm of low malignant potential. An operation with hand-assisted laparoscopic right nephroureterectomy and extravesical bladder cuff exision was carried out. The pathologic examination showed pure type of LELC, pT2N0.
Unlike lymphoepithelioma in the nasopharynx, immunohistochemical analysis of this urinary LELC was negative for the Epsteine-Barr virus. No disease recurrence was noted at 1-year follow-up. Only ten previous cases of LELC involving the renal pelvis have been reported. This is the first report of a renal pelvis LELC case in Taiwan.
