Self-Resolving Eruptive Keratoacanthomas After Full-Field Erbium Laser Resurfacing

Keratoacanthoma (KA) is a subtype of squamous cell carcinoma whose development has been linked to excessive sun exposure, immunosuppression, and trauma. Given the rapidly expanding therapeutic armamentarium for anti-aging modalities in dermatology, reports of KA secondary to invasive cosmetic procedures are on the rise. We present a case of eruptive KAs after full- eld ablative Erbium:YAG 2940 nm laser resurfacing of the face that resolved with minimal intervention. This case demonstrates the potential for a rare yet signi cant laser complication that may warrant discussion during the consenting process. J Drugs Dermatol. 2016;15(11):1453-1455..
