title: Keratoacanthoma arising from an excisional surgery scar.
abstract: A causal relationship between keratoacanthomas and a variety of preceding traumatic events has been postulated in the literature. We report a patient who developed a keratoacanthoma at the site of a recent cutaneous excision site, demonstrating that surgical trauma can precede the development of keratoacanthomas.
