Surgical treatment of recalcitrant warts.

Cryosurgery is the first choice for surgical treatment of viral warts. It is applied in two ways: with blister induction in extraplantar common warts and without blister induction in genital, filiform, and mosaic warts. Plantar and periungual warts are enucleated with a spoon or scraped off with a curet after preparatory focal electrocoagulation with a ball probe. Genital warts may be treated with "extracutaneous" electrosection and electrocoagulation.
