A severe and refractory case of anti-p200 pemphigoid resulting in multiple skin ulcers and scar formation.

Anti-p200 pemphigoid is a recently described autoimmune blistering skin disease that is characterized by the presence of autoantibodies against an unidentified 200-kDa dermal autoantigen. Most of the previous cases have been successfully treated using mild-to-moderate immunosuppressive therapies, which resulted in a good prognosis. We report here a severe and refractory case of anti-p200 pemphigoid that developed in a 53-year-old woman, in which blisters led to multiple skin ulcers, followed by severe scar formation. In the present case, methylprednisolone pulse therapy was effective enough to reduce the disease activity.
