Vesicular pemphigoid

Abstract

Seven patients had a chronic eruption of small vesicles that was initially considered to be atypical dermatitis herpetiformis. Histopathologic studies disclosed a subepidermal bulla that was compatible with either bullous pemphigoid or dermatitis herpetiformis. Immunofluorescence studies demonstrated deposition of IgG or C3, Or both, at the basement-membrane zone (BMZ) in six of seven patients. In four patients, circulating BMZ antibodies were detected also. We belive that these cases represent a vesicular form of bullous pemphigoid.
