title: In-situ hybridization for the diagnosis and typing of human papillomavirus.
abstract: The human papillomavirus (HPV) has been associated with the production of many skin and mucosal lesions, the development of squamous cell carcinoma of the genital areas, skin and aerodigestive tracts, and possibly adenocarcinoma of the uterine cervix. There are more than 60 known genotypes of HPV. Some genotypes have been associated with lesions that have none or minimal chances of malignant transformation; while other genotypes (especially types 16, 18, 31, 35, and 51) have been found in mild, moderate, and severe dysplasia, carcinoma in-situ or frank invasive carcinoma. HPV cannot be propagated in tissue cultures. The presence of the virus can be demonstrated by immunologic techniques, which are not sensitive enough with the present methodology, or by searching for the presence of the viral DNA by DNA or RNA hybridization techniques. Determining the viral genotype in the tissue involved will permit the separation of those lesions supposedly to be low risk from those associated with the high risk types. This knowledge may be helpful in the future to determine the appropriate management of patients infected with HPV.
