Diagnosis
Your doctor will ask about your symptoms and medical history, and perform a physical exam. He or she will refer you to a dermatologist, who specializes in conditions of the skin. Pyoderma gangrenosum is diagnosed by its appearance and by ruling out other causes of skin ulceration. Tests may include the following:
- Swabs to test for microorganisms
- Biopsy —removal of a sample of tissue to rule out other causes of the ulcers
- Blood tests
