Abstract
Hailey-Hailey disease is an autosomal dominant disorder caused by a mutation in the ATP2C1 gene and characterized by recurrent blisters, erosions, and crust in intertriginous areas. Currently, there are no curative treatments for Hailey-Hailey disease, and therapeutic strategies are focused on controlling skin microbial colonization, infection, and inflammation. Recent efforts have aimed to find therapies that target the biochemical pathway involved in the pathogenesis of this disease. Several case reports indicate the use of different biological agents to achieve long-term remission in patients with recalcitrant Hailey-Hailey disease. Tumor necrosis factor-alpha inhibitors have been used to treat and maintain remission in recalcitrant Hailey-Hailey disease patients, but additional reporting and studies are required. In this case series, we report three cases of recalcitrant Hailey-Hailey disease whose lesions were successfully controlled with adalimumab.
