A CASE OF ENDOSCOPICALLY POLYPECTOMISED CARCINOID TUMOR OF THE DUODENAL BULB

Abstract

This is a case report of carcinoid tumor at the duodenal bulb. A 54-year-old male with upper abdominal pain was referred to our hospital because of further evaluation of the polypoid lesion at the duodenal bulb which was detected at the other hospital. On upper GI series and endoscopy, semi-pedunculated polypoid lesion with the central depression about 15 mm in diameter at the anterior wall of the duodenal cap. The biopsies were endoscopically performed from the central depression. This polipoid lesion was carcinoid tumor histologically. Endorcopic polypectomy was performed because he refused the operation. This tumor was successfully removed and the resected polyp was 12 x 9 x 6 mm in size. Histologically, this tumor was mainly localized in the submucosa and partially invaded to the mucous layer. Furthermore, this tumor was encapsulated with the connective tissue and did not remain in the resected end. Therefore, it would be thought that this carcinoid tumor was completely resected by endoscopic polypectomy. However, careful observation should be needed as the metastasis of the tumor could not be completely ruled out.
