Linear IgA Bullous Dermatosis (C0406650)

Definition (MSH) Autoimmune disease characterized by subepidermal blisters and linear deposition of autoantibodies at the dermoepidermal junction. The accumulated autoantibodies are of IMMUNOGLOBULIN A and occasionally IMMUNOGLOBULIN G classes against epidermal BASEMENT MEMBRANE proteins. The dermatosis is sometimes associated with malignancies and use of certain drugs (e.g., VANCOMYCIN).
