Causes
Pemphigus is an autoimmune disorder. Normally, your immune system produces antibodies to fight off harmful invaders, such viruses and bacteria. But in pemphigus, the body produces antibodies that damage cells of your skin and mucous membranes.
Pemphigus isn't contagious. In most cases, it's unknown what triggers the disease.
Rarely, pemphigus is triggered by the use of angiotensin-converting enzyme inhibitors, penicillamine and other drugs.
