Abstract
- A primary duodenal carcinoid tumor causing carcinoid syndrome is rare. In case of accompanying carcinoid syndrome in a primary duodenal carcinoid tumor, it mostly suggests massive liver metastasis. In rare case, venous drainage of carcinoid tumor and systemic venous drainage are directly connected without passing through the portal system. Therefore, it is rare and interesting case which a primary duodenal carcinoid tumor accompanies carcinoid syndrome without liver metastasis. We experienced an occasion of a primary carcinoid tumor located in duodenal bulb in a 56 year-old woman. This patient came to our hospital because of intermittent diarrhea, epigastric pain and facial flushing. And it was surely diagnosed as carcinoid tumor by gastrointestinal endoscopic biopsy. She was hospitalized for surgery and we were able to confirm that carcinoid syndrome was accompanied through biochemical test. However, metastatic lesion was not found at liver, small and large intestine. We report this case with reference to documents due to rarity.
