Dupilumab in the Treatment of Dyshidrosis: A Report of Two Cases.

Dupilumab (Dupixent, Regeneron Pharmaceuticals and Sanofi Genzyme) is a novel biologic medication recently approved by the FDA for the treatment of moderate-to-severe atopic dermatitis in adults who have not achieved adequate control with topical medications. Dyshidrotic eczema is a distinct entity, often considered on the spectrum of atopic dermatitis, that primarily effects the palms and soles; it is often associated with considerable morbidity yet is frequently challenging to treat. We report two cases of recalcitrant dyshidrotic eczema treated successfully with dupilumab at standard dosing. Further studies to establish the efficacy of dupilumab in the treatment of dyshidrosis are warranted. <p><em>J Drugs Dermatol. 2018;17(3):355-356.</em></p>.
