[Linear IgA bullous dermatosis of children].

Linear IgA bullous dermatosis is an acquired autoimmune subepidermal blistering disease, characterized by linear IgA deposits at the basement membrane zone. Described in both children and adults, it occurs as tense pruritic vesicles and bullae in a "cluster of jewels" configuration with central crusting on an inflammatory elevated base. It is typically located on the face, anogenital region and trunk. Whilst the adult manifestations can be chronic, in children a spontaneous remission has often been reported. Our patient showed a spontaneous remission after 8 weeks of symptomatic topic treatment with methylprednisolone and oral cetirizine dihydrochloride.
