Duke dermatologists diagnose autoimmune skin diseases like pemphigus, pemphigoid, scleroderma, vasculitis, and lupus -- all of which occur when the body’s immune system attacks healthy skin. Our experienced doctors are dedicated to researching the causes of rare autoimmune skin diseases, testing new therapies, and providing relief from the itchy, blistering, or painful rashes that may affect the skin, mouth, and eyes.
