Abstract
A rare case of nonfunctioning islet cell tumor is reported with a view of the literatures. A 35-year-old woman was admitted because of epigastric discomfort. Laboratory data, ultrasonography, computed tomography, endooscopic retrograde pancreatography, and angiogram led to the diagnosis of the pancreas cancer located in the body. Distal pancreatectomy was carried out. A tumor measuring 4.5×4.5×4.0cm was located in the body of the pancreas. Histopathological findings revealed islet cell carcinoma.
