Abstract
BACKGROUND: Peristomal pyoderma gangrenosum (PPG) is a variant of pyoderma gangrenosum (PG). It results from a pathergy response to trauma from effluent from the ostomy or secondary to trauma caused by removal of the ostomy appliance adhesive in contact with the skin. Currently, no evidence-based guidelines for the management of PPG exist. This case study reports a dramatic response to crushed corticosteroid tablets in a patient who proved refractory to first- and second-line treatments of her PPG and several surgeries.
CASE: Ms T. was a 39-year-old woman with Crohn's disease who underwent several ileostomies, developed PPG, and failed treatment with adalimumab. Her PPG was successfully treated topically with crushed prednisone tablets.
CONCLUSION: We found that crushed corticosteroid tablets were an effective treatment of PPG, due to the ability to reduce pain and allow adhesion of the ostomy appliance.
