EBER expression of pure urinary bladder lymphoepithelioma-like carcinoma in two unique Asian patients.

We describe the 2 unique Asian cases of pure urinary bladder lymphoepithelioma-like carcinoma (LELCA). One patient had metastatic pelvic lymphoadenopathy and the other with superficial tumor. The EBER in situ hybridization both showed negative results despite racial or geographical factors might influence the peculiar susceptibility of individuals of Asian ancestry to Epstein-Barr virus-associated lymphoepithelioma-like carcinoma. The 2 patients were treated pertinently with satisfactory outcomes and intravesical BCG instillation is performed to prevent superficial LELCA recurrence rationally. Copyright 2005 S.
