Which of the following best describes management of peristomal PG?

• A. Broad-spectrum antibiotics
• B. Address underlying autoimmune component; topical anti-inflammatory; systemic steroids; injected local steroids
• C. Immediate surgical excision
• D. Only observation

Answer: (B)

Peristomal pyoderma gangrenosum is an inflammatory, immune‑mediated ulcer around a stoma. It’s not primarily an infection and can worsen with minor trauma (pathergy), so treatment focuses on suppressing the immune-driven inflammation rather than simply eradicating bacteria. Because PG is tied to an autoimmune process, addressing the underlying autoimmune component is important, and the regimen includes reducing systemic inflammation and local inflammation around the stoma. Using systemic steroids helps control the overall immune response, while topical anti-inflammatory agents calm the lesion on the skin, and injected local steroids provide targeted therapy to the peristomal area with less systemic exposure. This combined approach best matches the disease mechanism and offers the greatest chance of healing and symptom relief.

Broad-spectrum antibiotics aren’t the main treatment since the issue isn’t primarily infectious, though they may be considered if a secondary infection is present. Immediate surgical excision is avoided because PG lesions can worsen with trauma from surgery (pathergy). Observation alone would not address the active inflammatory process.
