Pemphigus (/ËpÉmfÉªÉ¡És/ or /pÉmËfaÉªÉ¡És/) is a rare group of blistering autoimmune diseases that affect the skin and mucous membranes.In pemphigus, autoantibodies form against desmoglein. Desmoglein forms the glue that attaches adjacent epidermal cells via attachment points called desmosomes. The least common and most severe type of pemphigus is paraneoplastic pemphigus (PNP). 2  This disorder is a complication of cancer, usually lymphoma and Castleman's disease. 3  It may precede the diagnosis of the tumor. 4  Painful sores appear on the mouth, lips, and the esophagus.
