BACKGROUND: Peristomal pyoderma gangrenosum (PPG) presents multiple challenges for healthcare providers. The diagnosis of PPG may be delayed, and it may be mistaken for an irritant dermatitis or an infection. Patients with ostomies secondary to inflammatory bowel disease (IBD) may experience PPG. Issues related to PPG include difficulty maintaining a seal of the ostomy pouching system and preventing contamination of the painful, necrotic ulcerations characteristic of this condition. Treatment focuses on the appropriate assessment of the ulcers, successful pouch application, and proper management of IBD through a collaborative effort of both dermatologists and certified WOC nurses (CWOCN). CASES: We treated 3 patients diagnosed with Crohn's disease (CD) who developed refractory PPG. All 3 were treated with a topical steroid lotion, prednisone, and adalimumab or a combination of these agents. Ostomy products and application were tailored to prevent leakage and protect areas of ulceration. All ulcers were healed within 6 months of our initial consultation. CONCLUSION: We successfully managed 3 patients with CD and PPG with appropriate ostomy care, including revision of the ostomy pouching techniques, topical steroid treatment, and treatment based on assessment of ulcer status by the dermatologist and the WOC nurse.
