title: Keratoacanthoma of the anus. Report of three cases.
abstract: Three cases of keratoacanthomas localized to the anal region are reported--one in the anal canal and two at the anal margin. The duration of the tumors before treatment was very short (three to nine weeks). Treatment consisted of local excision or curettage and electrocoagulation. No recurrence of the tumors was found at follow-up four to six years after treatment.
