Abstract
Anti-p200 pemphigoid is a recently defined subepidermal immunobullous disease. It is characterized by the binding of circulating IgG autoantibodies to the dermal side of 1 M NaCl split skin and by reactivity of these autoantibodies to a unique 200-kd antigen on immunoblot of dermal extract. On immunoelectron microscopic examination, these autoantibodies deposit at the lamina lucida-lamina densa interface. We describe the clinical, histologic, and immunopathologic features in a patient with anti-p200 pemphigoid, as well as his favorable response to treatment with systemic glucocorticosteroids and dapsone.
