Where do suture granulomas typically develop in peristomal skin?

• A. Reaction to suture materials
• B. Bacterial infection
• C. Nutritional deficiency
• D. Excess moisture

Answer: (A)

The main idea is that this is a foreign body reaction localized to the suture material left in peristomal skin. When suture fibers remain in or under the skin around a stoma, the body's immune system recognizes them as foreign. Macrophages gather and, sometimes, fuse into multinucleated giant cells to wall off the material, forming a granulomatous nodule right at the suture track in the peristomal tissue. This results in small, firm nodules exactly where the sutures were placed. It’s a sterile inflammatory response to the material itself, not an infection, nutritional issue, or moisture problem, which would present differently. If needed, treatment often involves addressing the suture (removing or replacing it) and managing the granuloma, rather than treating as an infection or moisture-related dermatitis.
