To study the relationship between pulmonary LELC and Epstein-Barr virus (EB
V) infection, we used in situ hybridization and immunohistochemistry techni
ques to detect the EBV-encoded small nonpolyadenylated RNA (EBER), latent m
embrane protein 1 (LMP1), and viral capsid antigen (VCA) in 32 cases of LEL
C and 19 cases of non-LELC lung carcinoma. Of the 32 cases, 30 (94%) showed
EBER positivity. Of the 30 EBER-positive pulmonary LELC cases, 16 and 7 ex
pressed LMP1 and VCA, respectively. In contrast with LELC, none of the 19 c
ases of a non-LELC lung carcinoma showed EBER-, LMP1-, or VCA infection and
pulmonary LELC. EBV infection may have an essential role in the tumorigene
sis of pulmonary LELC. EBV latent infection is the main status in pulmonary
LELC except for individual EBV entering into a lytic cycle.
