title: Isolation and characterization of papillomavirus DNA from nasal inverting (schneiderian) papillomas.
abstract: To elucidate the possible role of papillomaviruses as etiological agents in nasal inverting papillomas, DNA hybridization techniques were used. Total DNA from two nasal inverting papillomas was examined for the presence of DNA from human papillomavirus (HPV) types 6 and 11 under stringent conditions of hybridization. Both lesions contained DNA hybridizing with HPV 11. Restriction enzyme digestion and subsequent Southern blotting of the DNA samples revealed that one lesion contained viral DNA identical to HPV 11a. The DNA of the other lesion contained an extra 500 base pair insertion. These results provide definitive evidence for the first time for the association of HPV with nasal inverting papillomas.
