Refractory Hailey-Hailey disease successfully treated with sandpaper dermabrasion.

A 53-year-old woman presented with a 20-year history of pruritic dermatitis on the groin, axillae, inframammary folds, posterior aspect of the neck, and popliteal fossae. She was referred to our clinic by an outside facility after results from a punch biopsy diagnosed Hailey-Hailey disease (HHD). The patient had previously attempted treatment with many traditional noninvasive options with no success.
