VIPoma

>3cm diameter Luminal epithelium Inc cAMP productionNet fluid secretion into lumen VIPoma Diagnosis[Serum VIP] > 75 pg/mL (measured by radioimmu-noassay.) ; repeat if elevated. CT/ Octreotide scan/ EUS can help locate the lesion. VIP SYndrome (pancreatic cholera syndrome, Verner-Morrison syndrome)=watery diarrhea, hypokalemia, and hypochlorhydria or achlorhydria (WDHA) syndrome20% get facial flushing VIP secreted Lesion characteristicsLesions are solitaryThey are usually >3cm .They are usually in the tail.They usually have metastasized by dx.They can occur outside the pancreas. Prognosis The 5 year survival is 88%. Incidence of 1/10,000,000 Written by Dr Sebastian Zeki
