title: Oral lesions of epidermolysis bullosa acquisita.
abstract: Oral lesions with histologic evidence of subepidermal bullae are described in a patient with epidermolysis bullosa acquisita (EBA). Deposition of IgA, IgG, and C3 in the basement membrane zone and vasculitis with C3 deposits in vessel walls suggest the possible role of immune complexes in the pathogenesis of the disease.
