L10: Pemphigus

L10.1: Pemphigus vegetans

The immune system normally protects the body against pathogens and foreign substances. With some disorders, however, parts of the immune system target the body's own tissue or cells. You have a disorder that means your immune system is attacking certain components in your skin. The precise cause of the condition is not known.

The disorder involves growths and blisters forming on the skin or on mucous membrane.

Large folds of skin, for example in the armpit or the groin, are often affected. The mucous membrane in the mouth and nose may also be changed.
