Anogenital warts (condylomas) are caused by human papillomavirus (HPV) with >90% of the lesions caused by genotypes 6 & 11.
Patients who present with visible warts may also be infected with high-risk HPVs (eg types 16 & 18) which can cause subclinical lesions that are associated with intraepithelial neoplasia, cervical cancer and anogenital cancer.
Many HPV infections are subclinical, transient, and clear spontaneously within 12 months but may also remain latent and reactivate after several years.
