The epithelial lining of the anogenital tract is the target for infection by a group of mucosotropic viruses, the HPVs. Clinical or subclinical, transient or persistent, HPV infections are among the most common sexually transmitted diseases. ⋯ HPV infection is the direct cause of anogenital warts and a precursor event in the genesis of cervical cancer and other anogenital malignant tumors. Other HPV types commonly associated with anogenital warts are, for the most part, of low oncogenic risk.
