Nonfunctioning Pancreatic Islet Cell Tumor: A case report


A case of nonfunctioning pancreatic islet cell tumor is described. A 34 years old female patient had intermittent epigastric pain and nausea for 6 months and she had nothing suggestive of neuroendocrine symtoms. Physcial examination showed an epigastric mass which wae deepseated, nontender, and well-demarcated. The routine upper endoscopic evatuation was negative. Abdominal ultrasonography and computed tomography showed a well-defined round solid mass with multifocal necrosis but did not revealed the origin of the lesion. Endoscopic retrograde pancreatography showed upward and rightward displacement of the proximal body portion of main pancreatic duct with nonvisualization of the secondary branches of pancreatic duct, suggesting that the mass originated from the pancreas. Resection of the mass with partial pancreatectomy and Roux-en-Y pancreaticojejunostomy was perfomed and the pathology was coafirmed as nonfunctioning pancreatic islet cell tumor containing somatostatin by immunohistochemical technique.
