High-grade Dysplasia in Anogenital Warts of HIV-Positive Men.

Importance: Human papillomavirus (HPV)-induced anogenital lesions are very frequent in men who have sex with men (MSM) who are HIV-positive (HIV+). Anogenital warts (AGWs) are considered benign lesions caused by low-risk HPV-types, whereas anogenital dysplasias are potential cancer precursors associated with high-risk HPV-types. Both types of lesions can usually be distinguished clinically.
