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.

INTRODUCTION

Topical ruxolitinib is a potent Janus kinase (JAK) inhibitor that has demonstrated significant efficacy in treating an array of inflammatory skin conditions. While topical ruxolitinib has been most extensively studied in atopic dermatitis and vitiligo, recent reports have suggested its potential in treating other dermatoses. In this case series, we present four cases of refractory dermatological conditions that were successfully managed with topical ruxolitinib. These conditions include pediatric lichen sclerosus et atrophicus, morphea, perioral dermatitis, and notalgia paresthetica.

Case 1
A 9-year-old female presented with 6 years of recurring pruritic vaginal lichen sclerosus et atrophicus associated with occasional dysuria. Previously failed therapies included high potency topical steroids, crisaborole, and tacrolimus ointment. On exam, there was atrophy and hypopigmentation of the labia majora and minora with an erythematous patch extending from the vagina to the anus (Figure 1 A, B). Ruxolitinib 1.5% cream was applied to the affected areas twice daily for 6 weeks. On follow-up, the erythematous patch was significantly improved and the patient reported notable symptomatic improvement of both her pruritus and dysuria (Figure 1 C, D). 
 
 


A 13-year-old female with poorly controlled insulin-dependent diabetes mellitus presented with biopsy-proven morphea of the anterior lower legs, which had been present for years. Previously failed therapies included topical
