Significant Improvement of Persistent Hailey-Hailey Disease with Dupilumab: A Case Report

Hailey-Hailey disease is a rare, genetic blistering disease characterized by erythematous, scaly plaques in intertriginous regions such as the axillary, inframammary, and groin regions. The plaques cause discomfort and are difficult to treat. Treatment ranges from topical to systemic and surgical. Despite the variety of treatment options, Hailey-Hailey disease is notoriously difficult to treat with each patient responding uniquely to treatment. There has been evidence of patients with Hailey-Hailey disease experiencing improvement of symptoms with dupilumab injections. Dupilumab has several off-label uses, including allergic contact dermatitis, hand dermatitis, chronic spontaneous urticaria, and alopecia areata, showing promise for its use in dermatology outside of atopic dermatitis and prurigo nodularis. Due to its minimal side effects, dupilumab can be tried for Hailey-Hailey disease with little risk. We present the case of a 37-year-old female with recalcitrant Hailey-Hailey disease who noticed significant improvement on dupilumab.
