Novel Clinical Applications of Topical Ruxolitinib: A Case Series

Abstract

Topical ruxolitinib, a potent Janus kinase (JAK) inhibitor, has shown significant efficacy in treating inflammatory skin conditions. While its use has already been established in atopic dermatitis and vitiligo, recent reports suggest its potential efficacy in treating other dermatoses. Specifically, topical ruxolitinib may be an effective treatment option for refractory dermatological conditions that are inflammation-driven with dysregulated activity of cytokines implicated in the JAK/STAT pathway. In this case series, we present four novel clinical applications of topical ruxolitinib in treatment-resistant dermatological conditions. These cases include pediatric lichen sclerosus et atrophicus, morphea, perioral dermatitis, and notalgia paresthetica. All four patients reported noticeable symptomatic improvement and a significant improvement in the condition of their skin lesions. Our results suggest that ruxolitinib cream can successfully manage these conditions and may serve as supporting evidence for its formal evaluation.   J Drugs Dermatol. 2024;23(3): doi:10.36849/JDD.7696.
