Abstract
Human papillomavirus (HPV) infection of the lower genital tract is now considered the most important factor in the initiation of neoplasia. Human immunodeficiency virus (HIV) infection appears to alter the natural history of HPV-associated oncogenesis, but its impact on gynaecology has only recently been defined; the Centers for Disease Control (CDC) designated moderate and severe cervical dysplasia as a category B defining condition, and invasive cervical cancer as a category C defining condition of AIDS in 1993. Anal HPV infection and anal squamous intra-epithelial lesions have been found to be highly prevalent among HIV-positive homosexual men, and recent preliminary data suggest a relatively high prevalence among HIV-positive women as well. Moreover, HPV infection and associated lesions are also observed in body sites other than the anogenital area, particularly the skin and the oral cavity.
