An autoimmune disease is a health condition in which the body's immune system attacks the healthy tissues and organs instead of the harmful ones. This condition negatively impacts several parts of the body including the skin. There are several types of autoimmune skin diseases, namely, Behcet's disease, dermatitis herpetiformis, dermatomyositis, lichen planus, scleroderma, ocular cicatricial pemphigoid, vasculitis, pemphigoid and pemphigus.
