Five cases of nasal papillomatosis were studied clinicopathologically and virologically. In a case of recurrent papillomatosis of non-inverted type located on the nasal septum, human papilloma-virus (HPV) DNA was detected by dot blot hybridization with an RNA cocktail probe of mucosal HPVs. In Southern blot hybridization, the DNA hybridized with that of HPV types 6 and 11 but not with those of types 16 and 18. Its restriction endonuclease-cleavage patterns corresponded well to those of HPV type 6f. These results suggested that HPV type 6 would also be associated with nasal non-inverted papillomatosis.
