A case of linear IgA bullous dermatosis reported. A 32-year-old male with pruritic, papulovesicular eruptions on the whole body of 2 months' duration was examined. He had no history of diarrhea or fou]smellirig stool even though his diet cnntained gluten. A skin biopsy revealed subepidennal vesicles and papillary microabscesses infiltrated by many neutrophils and some eosinophils. Direct irnmunofluorescent examination of the perilesional skin showed a linear deposition of IgA along the basement mernbrane zone. The lesions responded rapidly to oral dapsone and topical steroid therapy but recurred whenever the oral mcdication was discontinued.
