Rapid clearance of extensive juvenile pityriasis rubra pilaris with ixekizumab.

Abstract

Juvenile pityriasis rubra pilaris is a rare inflammatory skin disorder currently without any FDA-approved treatments, and lesions can be refractory to conventional treatment with topical corticosteroids, methotrexate, and oral retinoids. We herein present a case of a 6-year-old boy who attained clearance of extensive juvenile pityriasis rubra pilaris within 2 weeks of starting ixekizumab therapy. Therapeutic effect has been durable at 6 months, and patient continues on therapy without adverse effects. Our case highlights a new, rapidly effective treatment option for pediatric patients with this rare condition.
