MADAM, Autoantibodies in pemphigus target preferentially desmoglein 1 (Dsg1) and Dsg3, and rarely desmocollins 1-3 (Dsc1-3). Pemphigus herpetiformis (PH) is one of pemphigus subtypes and characterized by pruritic annular erythemas with vesicles in the periphery, rarity of mucosal involvement and histopathological change of eosinophilic spongiosis. Recently, IgG anti-Dsc3 autoantibodies were suggested to cause skin lesion in a case of pemphigus vulgaris. In this study, we report the first case of concurrent bullous pemphigoid (BP) and PH with IgG antibodies to both Dsgs and Dscs.
