We are presenting the case of a 62-year-old man with a gastric tumor which turned out to be an undifferentiated carcinoma lymphoepithelioma type. The epithelial nature of the cells was confirmed by immunohistochemistry. The presence of Epstein-Barr virus, limited to the epithelial cells, was demonstrated by in situ hybridization. These findings confirm data from the literature and support the possible etiopathogenic relationship between Epstein-Barr virus and undifferentiated carcinoma lymphoepithelioma type of the stomach. We are unaware of any other report of this type of neoplasm in our country.
