High-Potency Topical Steroid Treatment of Multiple Keratoacanthomas Associated With Prurigo Nodularis

Cutis. 2021 Apr;107(4):221-222. doi: 10.12788/cutis.0221.

Abstract

Patients who present with multiple keratoacanthomas (KAs) associated with prurigo nodularis often pose a treatment challenge. These lesions often require aggressive treatment, such as Mohs micrographic surgery, surgical excision, electrodesiccation and curettage, intralesional steroid injection, and long-term acitretin. 5-Fluorouracil (5-FU) cream 5% has been shown to be effective; however, topical options are limited when 5-FU fails. We have found success using a high-potency topical steroid under occlusion, resulting in resolution of KAs and prurigo nodules.
