Carcinomas occurring in papillomas of the nasal septum associated with human papilloma virus (HPV).
Carcinomas arising in pre-existing sinonasal papillomas of the nasal septum are rare. To our knowledge only one case has been reported. We report two cases of carcinomas occurring in septal papillomas. In the first case a carcinoma developed in an exophytic papilloma 16 years after the first operation for a papilloma. In the second case a carcinoma was present at the first presentation within an inverted papilloma, and a metastasis had also developed. In the first case HPV type 6/11 was demonstrated by in-situ hybridisation and PCR in the original papilloma as well as in the recurrent papilloma and in the carcinoma. In the second case HPV type 18 was found in the nasal lesion as well as in the metastasis. All samples were examined for Epstein-Barr virus (EBV) by PCR, but with negative results. We believe that case one is the first reported case of carcinomatous transformation within an exophytic septal papilloma.
