title: Mohs micrographic surgery for an unusual case of keratoacanthoma arising from a longstanding tattoo.
abstract: This case report seeks to alert the reader to the possibility that the keratoacanthoma (KA) may develop in tattoo sites, specifically in red tattoo sites. We further wish to describe the senior author's treatment of such a lesion using Mohs micrographic surgery and a rotation flap to preserve the integrity of the original tattoo design in an area of minimal skin laxity. We briefly discuss the etiology of the KA and review potential tattoo reactions as presented in the literature.
