We encountered a case of lymphoepithelioma-like carcinoma (LELC) of the lung. A 71-year-old male had been followed up after low anterior resection due to sigmoid colon cancer in the surgical department of our hospital. Five years after the operation, a round tumor shadow, of about 1 cm in diameter, was pointed out in his right lower lung field on chest CT. Therefore, he was referred to our department. Metastasis or primary lung cancer was strongly suspected. However, the tumor was too small and too close to the PA to perform biopsy, and so we selected right lower lobectomy.
The pathological diagnosis was LELC of the lung. LELC is thought to be a rare disease in Japan. This tumor is believed to involve Epstein Barr (EB) virus infection in its etiology.
Our patient did not demonstrate EB virus on EBER-1 in situ hybridization, but antibodies of VCA and EBNA were both positive. These findings suggest that the patient had a past history of EB virus infection.
