Are [ Viral infection of herpes simplex , Epstein-Barr , varicela zoster , human papilloma , cytomegalovirus , or adenovirus related to sinonasal adenocarcinomas ]? Context: Several types of virus have been implicated in the development of head and neck tumors. However, until now sinonasal adenocarcinomas (ACN) have not been studied. 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.
