title: Premalignant lesions and cancers of the skin in the general population: evaluation of the role of human papillomaviruses.
abstract: To evaluate the role of human papillomaviruses (HPV) in the development of premalignant lesions and cancers of the skin in the general population, 314 biopsies obtained from 227 patients with benign neoplasms, premalignant lesions, and cancers of the skin and from 25 patients with squamous cell carcinoma of the lip were analyzed by Southern blot hybridization. DNA probes specific for various cutaneous and genital HPV types were used in hybridizations conducted under nonstringent or stringent conditions. HPV DNA sequences were only detected in eight specimens obtained from six patients: HPV 34 in one case of periungual Bowen's disease, HPV 36 and an as yet uncharacterized HPV in two cases of actinic keratosis, HPV 20 in one case of basal cell carcinoma, an as yet unrecognized HPV in one case of squamous cell carcinoma, and HPV 16 in one case of squamous cell carcinoma of the lip. None of the specimens of cutaneous horn and keratoacanthoma contained detectable HPV DNA. In contrast, HPV DNA sequences, mostly HPV 16, were detected in 13 of 23 cases of anogenital Bowen's disease and invasive Bowen's carcinoma. HPV DNA sequences were not detected in 90 cutaneous samples further analyzed by the polymerase chain-reaction technique, using amplification primers that contain conserved sequences among the genomes of HPV. These results strongly suggest that the known HPV types play only a minor role, if any, in skin carcinogenesis in the general population.
