Linear IgA bullous dermatosis

• Adult linear IgA disease is an acquired, autoimmune blistering disease that may present with a clinical pattern of vesicles indistinguishable from dermatitis herpetiformis, or with vesicles and bullae in a bullous pemphigoid-like appearance. This disease can often be difficult to treat even with usually effective medications such as rituximab.
• Childhood linear IgA disease is an acquired, self-limited bullous disease that may begin by the time the patient is age 2 to 3 and usually remits by age 13.
