Successful treatment of TNFα inhibitor-resistant pityriasis rubra pilaris with ixekizumab and acitretin

Abstract

BackgroundSeborrheic keratosis (SK) is a benign, common disease affecting mostly the middle aged and elderly population. SK lesions are characterized by pigmented skin growth, a warty surface, and sharp margins. Current therapies (curettage or cryotherapy) are invasive and painful. A non-invasive treatment is evaluated in this clinical study. Objectives: To assess the efficacy, safety, and tolerability of Nitrizinc Complex® topical solution (NZCS) for treatment of SK, after one to two topical applications.
