Abstract
Since HPV-57b has been identified by two different techniques in benign, premalignant, and malignant lesions of the nasal cavity, but not in cases of chronic sinusitis, HPV-57 should be recognised as at least a co-factor in the aetiology of nasal neoplasia. Paraffin sections of 22 histologically confirmed nasal tumours were screened by in-situ hybridisation with riboprobes specific for HPV-57b. Virus was demonstrated in 6 of 7 fungiform papillomas, 6 of 8 inverted papillomas, 1 of 3 inverted papillomas with dysplasia, and 2 of 4 inverted papillomas with carcinoma. The presence of HPV-57b was confirmed with the polymerase chain reaction, which identified an additional 4 positive samples, bringing the total to 86% positive specimens. The results underscore the importance of HPVs in the aetiology of cancers at extragenital sites.
