A 75-year-old woman with a sense of a full stomach was found in endoscopy of the upper digestive tract to have a submucasal tumor in the anterior wall of the duodenal bulb extending into the gastric antrum showing a cushion sign. Abdominal CT showed a 67×66 mm clear fatty density lesion in the duodenal bulb and the gastric antrum. Based on a diagnosis of lipoma arising in duodenal bulb, we coducted laparoscopic-assisted distal gastrectomy. The resected tumor was 12.0×6.5×3.0 cm, wide-based and covered with duodenal serosa. The tumor in the duodenal bulb and antrum was histologically confirmed to be lipoma originating in the submucosa. Giant duodenal lipoma exceeding 50 mm in maximum diameter have only been reported in 5 times in Japan and 9 times abroad. Only two have been treated by laparoscopically assisted resection of the duodenal lipoma in Japan.
