“…Discussions on the cytology of lymphoepithelioma are rare, and there are only few reports about the cytological presentation of these tumors in the nasopharynx, lungs, and salivary glands. Atypical and malignant cells in urine cytological examination were reported in the two cases of LELCB [38,39] and four cases of LELCU (including the current case) [9,13,14]. Cai and Parwani [40] reported that cytomorphologic features included large tumor cells with high nuclear to cytoplasmic ratios, vesicular chromatin, and prominent nucleoli, presenting as single cells or intermixed with inflammatory cells [40].…”

“…[6], and LELCs have been classified as a separate variant of urothelial carcinoma in the World Health Organization 2004 classification of urothelial tumors [22]. Besides arising in the bladder, LELCs arising from the renal pelvis [2,16–20], ureter [8–15], prostate [1], and urethra [2] were also reported. In order to characterize the malignancy, LELC is subdivided histologically based on the percentage of non‐LELC components.…”

“…The reports on nine patients including the present cases of primary LELCU from English and Slovenian populations were collected from 1998 to 2011. The clinical data are summarized and shown in Table 1 [7–14]. The histopathologic data are shown in Table 2.…”

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 [1], and urethra [2]. We present a case of LELC arising in the right proximal ureter of a 64‐year‐old male patient with hydronephrosis and nausea. Computed tomography demonstrated right ureter tumor. On biopsy, the patient was diagnosed with infiltrating urothelial carcinoma. An operation consisting of right nephroureterectomy and bladder cuff removal was carried out. The pathologic examination showed pure subtype of LELC, pT3N0. Unlike lymphoepithelioma in the nasopharynx, immunohistochemical analysis of this urinary LELC was negative for the Epstein–Barr virus. No disease progression was noted at 6 months’ follow‐up. Only eight previous cases of LELC involving the ureter have been reported, and a review of the available literature and a summary of ureter cases are presented here. This is the first report of a ureteral LELC case and third urothelial LELC cases [3] in Taiwan.

Analysis of genetic profiling, pathomics signature, and prognostic features of primary lymphoepithelioma‐like carcinoma of the renal pelvis

carcinogenesis of primary LELC may be due to different genetic variations, including single-nucleotide variants, insertion and deletions, structural variations, and repeat regions, which may provide the basis for clinical diagnosis and treatment. The prognosis of LELC in the upper urinary tract is similar to that of UUT-UC. We suggest that the focal subtype can serve as a prognostic factor for LELC of the upper urinary tract; however, further studies are required to confirm this.
