Cicatricial Pemphigoid

Cicatricial pemphigoid (also known as "Mucous Membrane Pemphigoid", "MMP", "Benign mucosal pemphigoid," "Benign mucous membrane pemphigoid," "Ocular pemphigus," and "Scarring pemphigoid") is a rare chronic autoimmune subepithelial blistering disease characterized by erosive skin lesions of the mucous membranes and skin that results in scarring of at least some sites of involvement.

Cicatricial pemphigoid has been referred to by a variety of designations based largely on its site of involvements, with examples of such terminology including "desquamative gingivitis," "ocular pemphigus," and "benign mucous membrane pemphigoid." However, currently "...such designations are thought to be confusing or somewhat misleadings (e.g., pemphigus in this context is a misnomer, and this disorder is hardly benign given the extent of morbidity it can cause)."
