Dermatitis herpetiformis with atypical clinical manifestations

Abstract

A case of 33-year old female with dermatitis herpetiformis, who manifested vast, erythema-edematous skin lesions with peripheral vesicles feston and rosette -shaped like. Skin lesions developed after dapson was discontinued in therapy. A diagnosis of dermatitis herpetiformis was verified, as clinical manifestations were suggesting a diagnosis of linear IgA bullous dermatosis. Direct immunofluorescence examination revealed granular IgA deposits (+++) in the dermal papillae. This result supported a diagnosis of dermatitis herpetiformis and excluded a diagnosis of linear IgA bullous dermatosis.
