Dermatitis herpetiformis


dermatitis herpetiformis: Dermatitis herpetiformis (DH) is a chronic autoimmune subepidermal bullous disease characterized by grouped pruritic lesions such as papules, urticarial plaques, erythema, and herpetiform vesiculae, with a predominantly symmetrical distribution on extensor surfaces of the elbows (90%), knees (30%), shoulders, buttocks, sacral region, and face of children and adults. Erosions, excoriations and hyperpigmentation usually follow. DH may also appear as a consequence of gluten intolerance.
