Pyoderma Gangrenosum
Symptoms of Pyoderma Gangrenosum
Most often, pyoderma gangrenosum begins as a red bump that may resemble a pimple or an insect bite. Less often, it begins as a blister. The bump or blister then becomes an open, painful sore (ulcer) that expands rapidly. The sores have a raised border that is dusky or purple. The sores can grow together to form larger sores. People often are left with scars after ulcers heal. People commonly have fever and a general feeling of illness (malaise). Pyoderma gangrenosum can also develop at other locations, such as in the abdominal wall around a colostomy or ileostomy opening in people who have inflammatory bowel disease, or on the genitals. In some people with pyoderma gangrenosum, areas other than the skin, such as the bones, lungs, heart, liver, or muscles, are affected.
