[ncbi.nlm.nih.gov], Tumoral content of these hormones was immunocytochemically confirmed on liver biopsy. Pancreatic polypeptide also functions as a hepatic glucose regulator. 15. Accessibility Pancreatic neuroendocrine tumors (PanNETs, PETs, or PNETs), often referred to as "islet cell tumors", or "pancreatic endocrine tumors" are neuroendocrine neoplasms that arise from cells of the endocrine (hormonal) and nervous system within the pancreas. High levels of pancreatic polypeptide are seen in several neuroendocrine tumors, such as carcinoid tumors and pancreatic polypeptidomas. Of various potential pancreatic endocrine hormones, only serum levels of pancreatic polypeptide were elevated. 1 in progress, 0 open to eligible people . This is the first reported case of gastric PP-producing endocrine tumor. Our report describes a 46-yr-old woman who presented with watery diarrhea in the presence of multiple endocrine neoplasia type I (MEN I) syndrome. Three years later she developed gallstone pancreatitis with the subsequent development of a pancreatic pseudocyst. The only pancreatic cells that make PP are rare neuroendocrine cells in the Islets of Langerhans (an already tiny fraction of the pancreas). The function of PP is to self-regulate pancreatic secretion activities (endocrine and ��� Final pathology documented a pancreatic endocrine tumor with immunohistochemical staining demonstrating the presence of pancreatic polypeptide. The immunohistochemistry study of the tumor for VIP-immunoreactivity (VIP: vasoactive intestinal polypeptide) was markedly positive, and also stained slightly positive for other peptides, including pancreatic polypeptide (PP), calcitonin, glucagon, and neuron-specific enolase (NSE). In: International Journal of Gastrointestinal Cancer, Vol. Pancreatic Polypeptide, ECL - Detection of Pancreatic Polypeptide is used in the assessment of pancreatic tumor burden and to assist in the early diagnosis of pancreatic endocrine tumors. The present case illustrates the symptomatology that may be associated with pancreatic polypeptide-secreting endocrine tumors of the pancreas. FOIA [ncbi.nlm.nih.gov], Watery diarrhea, hypokalemia, achlorhydria (WDHA) syndrome can also be caused by VIPomas. [ucdavis.pure.elsevier.com], An abdominal CT scan revealed a 3 cm soft tissue mass arising inferiorly from the tail of the pancreas. At exploration for drainage of the pseudocyst, intraoperative ultrasound identified a 6-mm tumor in the distal pancreas that was resected.

[books.google.com], Epidemiology United States Neoplasms of the endocrine pancreas occur in two distinct epidemiologic groups. People who have neuroendocrine tumors (NETs) have higher levels of this substance. Pancreatic polypeptide is secreted by special cells in your pancreas. Insulin, glucagon, gastrin, vasoactive intestinal polypeptide and human pancreatic polypeptide were present in only trace quantities. 1 Pancreatic Polypeptide (PP) Pancreatic polypeptide (PP) is a 36-amino-acid peptide that is known to stimulate the gastric secretion of HCl and pepsin (see Table 6-1). HPP : Pancreatic polypeptide (PP) is secreted by the pancreas in response to hypoglycemia, ingestion of food, or "sham" feeding (food is chewed, but not swallowed) secondary to vagal nerve stimulation.
