Clinical treatment options for peristomal pyoderma gangrenosum.

Pyoderma gangrenosum is a rare debilitating skin disease of unknown aetiology that manifests itself as painful lesions and is often associated with inflammatory bowel disease. Stoma care nurses will encounter it directly around the stoma as peristomal pyoderma gangrenosum (PPG). There are many case reports of varying methods of treatment for PPG, although none have proven to be efficacious in all circumstances. When these lesions develop in the peristomal area, treatment must be balanced with the need to maintain an intact stoma appliance.
