Multiple eruptive keratoacanthomas arising in a tattoo

Abstract

Keratoacanthomas are rapidly growing, keratinizing, epithelial neoplasms that tend to spontaneously involute and are rarely multiple or eruptive. There is still disagreement on whether or not this condition is a malignancy or a benign epidermal neoplasm; nevertheless, its appearance on tattoos has been reported in rare instances. When waiting for spontaneous involution is not an option, surgery is the preferred treatment. Other therapeutic modalities used for the treatment of this condition include radiotherapy; cryotherapy; laser therapy; and multiple intralesional, topical, and systemic agents. The authors report a patient who developed multiple, eruptive keratoacanthomas in the red ink portions of a tattoo and was successfully treated with acitretin.
