Human papillomavirus and carcinoma of the mucosal surfaces of the head and neck

Abstract

Human papillomavirus induced cervical cancer is the fourth most prevalent malignancy affecting females globally. Over the past two decades scientific information unveiled an increasing role for the virus in the pathogenesis of malignancies developing from the mucosal surfaces of the oropharynx. It is feasible to postulate that we may be in the beginning of a global pandemic of oropharyngeal cancer if the mode of transmission of the virus is taken into account. The main goals of this manuscript are to present a brief summary of the mechanisms of human papillomavirus induced malignant transformation, provide guidelines for the microscopic diagnosis of high risk human papillomavirus involvement in mucosal biopsies and highlight the implications thereof in cancers of the mucosal surfaces of the head and neck.
