A woman with either pemphigus or pemphigoid, two blistering disorders, gazes into the distance.

If you have unexplained blisters appearing on your body, pemphigus and pemphigoid could be to blame. These are autoimmune blistering disorders that are not contagious. 

“These conditions are caused by an immune system gone awry and manifest as blisters in the skin or membranes such as the mouth, nose and eyes,” says Yale Medicine dermatologist Mary M. Tomayko, MD, PhD. “These are extraordinarily rare diseases,” she says.
