The aim of this study is to screen a series of ACN for the presence of a number of viruses known to play a role in cancer.', 'Viral DNA sequences of herpes simplex virus, Epstein-Barr, varicela zoster, human papilloma, cytomegalovirus, and adenovirus were analysed by PCR in 37 primary ACN.', 'Three tumors (8.1%) were positive for Epstein-Barr virus and 1 case (2.7%) for cytomegalovirus.'] Are [ Viral infection of herpes simplex , Epstein-Barr , varicela zoster , human papilloma , cytomegalovirus , or adenovirus related to sinonasal adenocarcinomas ]?
