Anal warts are benign tumours of the epidermis induced by inoculation of specific papilloma viruses; they are usually transmitted by sexual activity.

Majority of warts cause little physical discomfort. Sometimes the warts may be associated with irritation and soreness. Bleeding from the anus may indicate at internal lesions (1).

If the immune system is compromised, they can present major problems to cure.

The general principles of management of warts is presented in the menu below. Note that if surgical excision under local anaesthetic is the only practical treatment option, then normal skin between the warts needs to be carefully preserved so as to avoid delays in healing and anal canal stenosis.

It is prudent to consider the HIV and hepatitis B status of the patient, and counselling as to the wart presence and treatment of sexual partners.
