The bullae are formed by an immune reaction, initiated by the formation of IgG [citation needed] autoantibodies targeting dystonin, also called bullous pemphigoid antigen 1, [6] and/or type XVII collagen, also called bullous pemphigoid antigen 2, [7] which is a component of hemidesmosomes. A different form of dystonin is associated with ...
It is also commonly diagnosed by specialists practicing otolaryngology- head and neck surgery, periodontists, oral and maxillofacial surgeons, and eye doctors, as lesions can affect the eyes and mucous membranes of the oral cavity. Intraorally, it resembles the more common diseases lichen planus and mucous membrane pemphigoid. [13]
Pemphigus erythematosus (Senear-Usher Syndrome) is a rare form of pemphigus with features of pemphigus foliaceus and lupus erythematosus. [1] [2] It was first described by Francis Senear and Barney Usher at the University of Illinois College of Medicine in 1926. [3]
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, [1] however unlike pemphigus, pemphigoid does not feature acantholysis, a loss of connections between skin cells.
The number of target antigens varies on a case by case basis. The variability is likely what accounts for the different presentations of PNP. Through immunoprecipitation, target antigens have been found to include desmoglein-3, desmoglein-1, envoplakin, periplakin, desmoplakin 1, desmoplakin 2, and bullous pemphigoid antigen I.

Mucous membrane pemphigoid is a rare chronic autoimmune subepithelial blistering disease characterized by erosive lesions of the mucous membranes and skin. [3] It is one of the pemphigoid diseases that can result in scarring.
