We describe a rare pulmonary tumor of a 73-year-old Japanese man. The tumor was located in the left upper lobe and measured 35×25×25 mm. The histological diagnosis was lymphoepithelioma-like carcinoma (LELC) on routine HE-stained sections, whereas the tumor cells did not prove to possess the EBV genome using in situ hybridization for EBER-1. Although this case was not classified into the LELC category based on 2004 WHO classification, a few Caucasian cases reported from Western countries were all EBV-negative LELC before publication of the 2004 WHO classification. Our case must represent the same pattern of these Caucasian cases. Moreover, our case showed tumor-infiltrating lymphocytes possessed the EBV genome. There are no reports of tumor infiltrating lymphocytes of pulmonary LELC with the EBV genome. However, there are some reports of tumor-infiltrating lymphocytes possessing the EBV genome in pulmonary carcinoma of other histological typings. On the other hand, some reports have demonstrated EBV genomes in the tumor cells of pulmonary non-LELC. Therefore, we conclude that histological formation of pulmonary LELC does not require the EBV genome, although EBV might be related to tumorigenesis of some cases of pulmonary carcinoma.
