Pyoderma gangrenosum (PG). PG is an uncommon condition that occurs almost exclusively in patients with inflammatory bowel disease. It is more common in women and peaks in the third to sixth decades of life. Lesion borders are purplish in colour with an erythematous edge. The ulcer progresses, leading to a painful, necrotic wound. It usually responds to steroids, and standard dressing after removal of the necrotic tissue, and good colitis control.
