Abstract
We report a 20-year-old man who presented with abdominal discomfort for 2 months. Colonoscopy showed skip areas with ulceration, resembling Crohn's disease. Biopsies showed chronic inflammation and a non-necrotizing granuloma. An adult pinworm was found in the lumen from an uninvolved segment. The patient responded to mebendazole.
