Secondary spread to the anal region is not uncommon. Treatment Several different methods of treatment have been described and should be adapted to the individual patient. Repeated application of chemical agents such as podophyllin is suitable for small numbers of polyps outside the anal canal. Warts persisting after a month are unlikely to respond to further applications. Persistent and more extensive warts are treated by surgical excision or ablation by diathermy. Infiltration of the affected area with a weak solution of adrenaline helps show the individual lesions, which can be picked off with a fine scalpel, preserving the intervening skin. Coagulation by using diathermy or laser is also effective but causes greater discomfort afterwards. Recurrence is common so it is important to treat coexistent genital lesions and sexual partners. Advice about barrier contraception should be given where appropriate.
