Islet cell tumor of the pancreas with reversible watery diarrhoea and achlorhydria.
Saint Louis Missouri, USA Computed tomogram of 28 patients (15 male, 13 female) with pathologically proven diagnosis of Non-Functional Islet cell tumor of the pancreas performed at our institution between March 2002-July 2006, were retrospectively analyzed by two abdominal radiologists in consensus with regard to size, site of pancreatic origin, calcification, pattern of enhancement, local or vascular invasion and distant Metastases; size, number, pattern of enhancement, vascular invasion, and biliary ductal dilatation.
Solid and papillary epithelial neoplasm of the pancreas; differential considerations include: nonfunctioning islet cell tumor, pancreatoblastoma and complicated pseudocyst
One patient with occult cancer also had an islet cell tumor of the pancreas thought to be benign; 3 additional patients had clinically undetected neoplasms of benign or indeterminate malignant potential (pancreas, central nervous system) which may have contributed to death (Table 4).
Nonfunctioning islet cell tumor with a unique pattern of tumor growth.
Other, less common causes of pancreatic masses include solid tumors (such as islet cell tumor [ICT]), lymphoma, mesenchymal tumor, metastasis to the pancreas as well as a variety of cystic lesions.
The ultrasonographic findings were consistent with a pancreatic cystic neoplasm, and the differential diagnosis included solid pseudopapillary neoplasm and nonfunctioning islet cell tumor.
Pancreatic NETs are also called islet cell tumors, because the endocrine cells of the pancreas are commonly located in clusters, anatomically called islets of Langerhans [1].
Gelatinases and inhibitors of gelatinases in pancreatic islets and islet cell tumors.
The term is not used for several other tumors, such as pancreatic islet cell tumors and small cell carcinomas.
