RESUMEN
Undifferentiated squamous cell carcinoma, lymphoepithelioma-like carcinoma of salivary glands is rare disease, the incidence of which is highest among the Inunit of Greenland and North America. By the way, the relation of Epstein-Barr virus(EBV) with this tumor has not been studied to any great extent here in Korean because of rare number of cases. Correlations between lymphoepithelioma and EBV have been investigated with morphologic and pathologic evaluation. Recently, nonnasopharyngeal neoplasms, which have morphologic features identical to those lymphoepithelioma, called lymphoepithelioma- like carcinoma(LEC). We experienced the treatment of lymphoepithelioma-like carcinoma arising from the parotid gland and a case is presented with the review of literatures.
