Linear immunoglobulin A bullous dermatosis is a rare entity with frequent spontaneous resolution. It usually presents in children with average age of 4.5 years. Its incidence is about 0.5-2.3 cases/million individuals/year. It is, after dermatitis herpetiformis, the most frequent paediatric blister disorder. It usually appears in bouts with acute development of vesicles in strings of pearls; affecting the perioral area and genitalia. Diagnosis is based on the clinical signs and symptoms and biopsy of the skin with subepidermal blister and a linear band of immunoglobulin A in the direct immunofluorescence. Often, diagnosis is made late because of the unawareness of this disease.
