Abstract:
A 81-year-old woman admitted with general fatigue was found to have a giant polyp in the gastric antrum by endoscopy. The polyp prolapsed into the duodenum through the pylorus. Angiographic examination of the abdomen revealed the polyp to be about 90×35 mm in size. Laparotomy was performed. It was finally diagnosed as heterotopic Brunner's gland adenoma which had a stalk on the antrum of the stomach. Heterotopic Brunner's gland adenoma is rare. Only 3 cases including the present case have been reported in Japan.
