Hailey‐Hailey disease successfully treated with vitamin D oral supplementation.

Hailey‐Hailey disease (HHD) also known as familial benign chronic pemphigus is a rare autosomal dominant genodermatosis. HHD treatment is often not satisfactory and hence, various modalities of treatment have been tried. We describe the case of a 37‐year‐old woman with a 2 years history of macerated erythematous plaques along with erosions, fissures, and crusts located on axillae and submammary areas, successfully treated with only oral supplementation of vitamin D (800 I.U./die) for 3 months. We reported this case to suggest that oral vitamin D may be enumerated in the various treatments proposed for HHD so far due to its rapid efficacy on skin lesions and symptoms. [ABSTRACT FROM AUTHOR]
