[Genital warts in HIV-infected individuals]

Anogenital warts (condylomata acuminata) are much more frequent in human immunodeficiency (HIV)-positive patients compared to HIV-negative individuals. Anogenital warts of HIV-infected patients differ from those of HIV-negative individuals with respect to their spread, occurrence on more unusual anatomical sites, human papillomavirus (HPV)-type spectrum, tendency to recur, and risk of malignant transformation. Between 18 and 56% of anogenital warts of HIV-positive patients harbor high-grade dysplasia. Therefore, anogenital warts of HIV-infected patients should be preferentially treated with ablative methods and should be evaluated histopathologically. Gender-neutral prophylactic HPV vaccination of HPV-naive boys and girls could also lead to a significant reduction of anogenital warts in this patient group in the future.
