Circulating auto-antibodies in the human body can target normal parts of the skin leading to disease. This is a list of antigens in the skin that may become targets of circulating auto-antibodies leading to the various types of pemphigus.
Pemphigus is a rare group of blistering autoimmune diseases that affect the skin and mucous membranes. The name is derived from the Greek root pemphix, meaning "pustule".
Pemphigoid is a group of rare autoimmune blistering diseases of the skin, and mucous membranes. As its name indicates, pemphigoid is similar in general appearance to pemphigus, but, unlike pemphigus, pemphigoid does not feature acantholysis, a loss of connections between skin cells.
Epidermolysis bullosa acquisita, also known as acquired epidermolysis bullosa, is a longterm autoimmune blistering skin disease. It generally presents with fragile skin that blisters and becomes red with or without trauma. Marked scarring is left with thin skin, milia and nail changes. It typically begins around age 50-years.
Mucous membrane pemphigoid is a rare chronic autoimmune subepithelial blistering disease characterized by erosive lesions of the mucous membranes and skin. It is one of the pemphigoid diseases that can result in scarring.
