Peristomal pyoderma gangrenosum (PPG) is a somewhat uncommon and challenging condition to diagnose and treat, as no evidence-based guidelines or standard treatments exist. PPG can occur after the surgical placement of an ostomy, impacting approximately 0.5 to 1.5 people per million annually, and accounts for 15% of pyoderma gangrenosum cases. Effective management of PPG requires local and often systemic immunosuppression and topical wound care, which is compatible with being applied beneath an ostomy pouch.
