Anal warts (aka condyloma acuminata) are caused by an infection of the human papillovirus (HPV). Although troubling for the patient, up to 75% of cases respond well to medical management with topical medications such as acetic acid and podophyllin, topcial flourouracil, and topical interferon and imiquimod.
More recalcitrant cases may require excision or fulguration.
Anal warts are considered a sexually transmitted disease and risk factors include unprotective receptive anal intercourse, multiple sexual partners, and immunosuppression.
