abstract = "Human papillomavirus (HPV) is associated with human neoplasms of squamous epithelium. Squamous papillomas and verrucous carcinomas are two types of squamous neoplasms of the larynx that present difficult problems in differential diagnosis. Using in situ hybridization with biotinylated DNA probes, we examined benign squamous papillomas and verrucous squamous carcinomas of the larynx for the presence of HPV. Forty-two biopsy specimens from 18 patients with laryngeal papillomas and 11 biopsy specimens from seven patients with verrucous carcinomas were obtained from the files of Pennsylvania Hospital, Philadelphia, PA. Tissue sections were hybridized with an HPV DNA cocktail. The HPV-positive cases then were subtyped further with DNA probes specific for HPV subtypes 6/11, 16/18, and 31/33/35. All benign squamous papillomas (42 of 42) were positive for HPV subtype 6/11. None of the verrucous carcinomas contained demonstrable HPV (none of 11). Some of the squamous papillomas were recurrences, which shows the persistence of the virus. These results indicate that laryngeal papillomas may be related to HPV, but verrucous carcinomas are not.",
