Pyoderma Gangrenosum

This is characterised by a full-thickness, rapidly enlarging, painful ulcer with blue/purple undermined borders. It's associated with IBD, RA, and Leukaemia, and is triggered by injury to the skin.

It's different from a simple skin ulcer as it usually develops soon after surgery/skin injury, and grows very rapidly with an oedematous purple ridge, causing a lot of pain.


It's managed with:

  • Surgical debridement

  • Abx

  • Steroids
