Spontaneous resolution of eruptive papules following ablative laser resurfacing-Case report and review of laser-associated eruptive keratoacanthomas.

Abstract

Keratoacanthomas (KAs) following laser treatment are a rare, but well-described entity. Herein, we describe a case of eruptive keratoacanthoma (KA) following laser resurfacing treatment and aim to better characterize laser-associated KAs. A literature search was performed on PubMed reviewing laser-associated KAs including various characteristics: epidemiology, history of skin cancer, location, and number, type of laser, as well as the management and outcome. Fractional ablative was the most common type of laser triggering KAs, and most cases presented within the first month following treatment. The majority of cases of laser-induced KA had a prior history of a malignant or premalignant skin neoplasm. Laser-induced KAs were treated using modalities similar to KAs arising in other contexts. Clinicians need to be knowledgeable and prepared to understand, and manage complications following laser treatments, as rare as they may be, including KAs.
