Human papillomaviruses cause almost all cervical carcinomas, but HPV infections have recently been established as a major etiologic factor for a subset of cancers arising from the oropharinx, including the base of tongue, tonsil, and other parts of the pharinx. Certain types of HPV are considered carcinogenic in humans: HPV 16 and HPV 18 are the most carcinogenic types; HPV 31, 33, 35,39,45,51,52,56,59,66 and 68 also are included in the group of carcinogenic HPV types (1,2,3,4,5). HPV 6 and 11 are associated with genital warts and papillomas are not believed to be carcinogenic (6). The aim of this paper is to show a case of a benignant papilloma of the nasal fossa due to a HPV 11 infection. |
