Hailey-Hailey disease: effective treatment with topical cadexomer iodine.

Hailey-Hailey disease (HHD) or familial benign pemphigus is known to have a chronic relapsing-remitting course. Conventional treatment with topical steroids and antibiotics often yield unsatisfactory results. We report a case of HHD treated successfully with topical cadexomer iodine powder. Cadexomer iodine may be a useful therapy for recalcitrant cases of HHD.
