Description

Pemphigus is a disease that causes blisters and sores on the skin or mucous membranes, such as in the mouth or on the genitals.

Pemphigus can occur at any age, but it's most often seen in people who are middle-aged or older. It tends to be a long-lasting (chronic) condition, and some types can be life-threatening without treatment. Treatment with medication usually controls it.
