The management of anal warts

摘要

The incidence of condylomata acuminata, commonly known as anogenital warts, is increasing. In the United Kingdom it is the most common sexually transmitted disease; in 1997 over 50 000 new cases were reported, accounting for 22% of all diagnoses made in genitourinary medicine clinics. In the United States an estimated 1% of adults who are sexually active have lesions. These benign warts are caused by human papillomavirus; genotypes 6 and 11 are found in over 90% of cases. However, some patients are concurrently infected with onco-genic types of the virus, principally genotypes 16 and 18, which may induce multifocal anogenital intraepi-thelial neoplasia and cervical cancer. Although people with anogenital warts present to many different disciplines guidelines for management have recently been published by the Medical Society for the Study of Venereal Diseases of the United Kingdom and the European Course on Human Papilloma Virus Associated Pathology Group.
