VIPoma

 
an endocrine tumor, usually a type of islet cell tumor, that produces excessive amounts of vasoactive intestinal polypeptide, producing severe diarrhea, hypokalemia, and hypochlorhydria, leading to renal failure that can be fatal.

(vi-pō'mă),
An endocrine tumor, usually originating in the pancreas, which produces a vasoactive intestinal polypeptide believed to cause profound cardiovascular and electrolyte changes with vasodilatory hypotension, watery diarrhea, hypokalemia, and dehydration.

A neuroendocrine tumour of tissue that stains for chromogranin A and is rich in vasoactive intestinal peptide, hence the name. The condition features persistent large-volume watery diarrhoea.
