Linear Ig A bullous dermatosis (LABD) is an acquired autoimmune subepidermal blistering disorder with linear deposits of IgA along the basement membrane zone. Its cause is unclear, although it appears to have an immune-mediated basis. Idiopathic, systemic disorder-related, and rarely drug-induced forms of LABD have been described. We describe a case of LABD associated with interferon-α 2A used for the treatment of Kaposi’s sarcoma.
