Pyoderma gangrenosum (pie-oh-DER-muh gang-ruh-NO-sum) is a rare skin condition that causes painful open sores (ulcers). The ulcers often begin at the site of a minor puncture or cut and then expand rapidly. While pyoderma gangrenosum ulcers can occur anywhere on your body, they most commonly occur on the legs. People who have autoimmune diseases, particularly inflammatory bowel disease or rheumatoid arthritis, are at higher risk of pyoderma gangrenosum.
