Rapid development of keratoacanthomas after a body peel

Abstract

Resurfacing techniques have been traditionally limited to the face because of a lack of predictability and standardization for peeling nonfacial skin. There is a need for medical and surgical intervention for treating nonfacial skin that is actinically damaged. Medium-depth chemical peels (Jessner +35% trichloroacetic acid) remove the photodamaged epidermis to stimulate the production of new collagen in the dermis and remove lesions associated with facial actinic damage, including lentigines and actinic keratoses. Widespread actinic damage is common on the arms and chest. A 70% glycolic acid gel plus 40% trichloroacetic acid peel (Cook Body Peel) is a controlled peel that predictably enables peeling of nonfacial skin in a uniform and safe fashion with specific clinical endpoints. An unusual complication of this body peel is reported.
