Pyoderma gangrenosum is most common in people in their 40s and 50s, but can occur at any age. It's also associated with inflammatory conditions, including:

  • Ulcerative colitis. This disease of the large intestine causes chronic inflammation of your large intestine.
  • Crohn's disease. Like ulcerative colitis, Crohn's disease causes long-term inflammation that can occur anywhere along your digestive tract.
  • Rheumatoid arthritis. Rheumatoid arthritis refers to a condition in which the thin membranes surrounding your joints become irritated and inflamed.
