Linear IgA bullous dermatosis in a child successfully responding to oral antibiotics

Linear IgA bullous dermatosis (LABD) is a rare, chronic, autoimmune bullous dermatosis affecting young children and adults. The exact pathogenesis of this disease is still unknown, although both humoral and cellular immune response are involved. Clinically, it may show heterogeneous skin manifestations. However, it is characterized histologically by linear immunoglobulin A (IgA) deposits over the basal membrane, causing subepidermal blisters. Studies on LABD are relatively sparse and most of the publications are small series or single case reports. Several treatments are reported in literature, however, they should be used with care due to the risk of side effects. We report a case of linear IgA dermatosis with generalized lesions in a 7 year old child, with good outcome under dermocorticoids and antibiotics
