　A 66-year-old woman with anemia visited our hospital for more detailed examination of an elevated lesion in the duodenum. A giant pedunculated polyp in the bulb was found by upper gastrointestinal endoscopic examination and was resected by endoscopic polypectomy. The resected specimen was 50×30×18 mm in size and pathologically diagnosed as a Brunner's gland hyperplasia. To toe best of our knowledge, the biggest Brunner's gland hyperplasia which was resected by endoscopic polypectomy, reported in Japan was 60 mm in size. But the polyp of our case was the biggest in volume.
