PDLIM7 and oral cavity neoplasm: However, in contradistinction to Barbera et al. who detected EBV in the open-lung biopsy specimens of 9 of 14 patients with LIP [24] and another study that detected EBV DNA in 80% of lung specimens from HIV-positive children with LIP [21], we failed to detect any difference in EBV frequency using an LMP-1 immunoassay.
