An ulcer is a sore that develops on the skin (such as the skin around the ankles) or on a mucous membrane (such as inside the mouth, stomach, or intestines). Ulcers can be shallow or deep and can destroy the skin or the membrane where they develop.
Ulcers can be caused by some types of infection, injury, or cancer.
