title: Palmar purpura: an atypical presentation of childhood dermatitis herpetiformis.
abstract: Dermatitis herpetiformis (DH) is seen most commonly as a pruritic, papulovesicular eruption in young children or adolescents. Differentiation from other bullous diseases of childhood may be difficult. We report the first case of an adolescent in whom pruritic, palmar, purpuric macules and papules were the only manifestations of DH. The patient later developed typical vesiculobullous extensor lesions and symptomatic gluten-sensitive enteropathy (GSE). All lesions and GSE symptoms resolved with dapsone and a gluten-free diet. Our purpose is to illustrate an unusual presentation of pediatric DH.
