LAP3 and fibroepithelial polyp: Similarly, Perera et al. [121] also report lower abundance and species diversity of periodontal pathogens in neoplastic tissues in a case–control study of OSCC and fibroepithelial polyps (FEP); they also note a greater more abundance of pro-inflammatory bacterial features, including lipopolysaccharide biosynthesis and peptidases, in OSCC tissues.
