title: [Human papillomavirus and nasosinusal inverted papilloma].
abstract: Eight inverted papillomas were evaluated for the presence of human papillomavirus (HPV) DNA. The techniques used were Southern Blot Hybridization in five cases and Polymerase Chain Reaction (PCR) in three cases. All eight lesions contained the characteristic features of inverted papillomas. Two lesions showed areas of dysplastic change and one lesion contained koilocytes. In three patients, invasive squamous cell carcinomas were found. The presence of HPV was noted in one of these specimen of inverted papilloma with squamous cell carcinoma. Specific testing for HPV types 6, 11, 16, 18 and 33 on this specimen was negative, thus indicating that the specimen is associated with a different HPV type. The results of this study, with only one case of positive HPV testing, leads us to question the precise role of HPV as an etiological agent in nasal inverted papillomas. The fact that this single positive case did not test positive for the HPV type 16 suggest that this is not the only "high risk" HPV type associated with the progression of inverted papilloma to a carcinoma.
