VIPoma

(redirected from Vasoactive Intestinal Peptide-Producing Tumor)

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·Po·ma

(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.

VIPoma

/VIP·oma/ (vĭ-po´mah) an endocrine tumor, usually an islet cell tumor, that produces vasoactive intestinal polypeptide, causing a syndrome of watery diarrhea, hypokalemia, and hypochlorhydria, leading to potentially fatal renal failure. Alternatively, vipoma.

/vip·oma/ (vĭ-po´mah) VIPoma.

VIPoma

[vipō′mə]
a type of pancreatic tumor that causes changes in secretion of vasoactive intestinal polypeptide (VIP). VIP causes dilation of blood vessels throughout the body and secretion of fluid and salt in the intestinal tract, resulting in diarrhea. The VIP effects mimic the symptoms of cholera (severe diarrhea, hypokalemia, and hypochlorhydria) and can result in death from dehydration and subsequent kidney failure if treatment is not begun early. See also vasoactive intestinal polypeptide.
A vasoactive intestinal peptide-producing tumour of the pancreas associated with a cholera-like syndrome in absence of gastric hypersecretion

VIPoma

Oncology A VIP–vasoactive intestinal peptide-producing tumor of the pancreas, which is associated with a cholera-like syndrome in absence of gastric hypersecretion. See VIPoma syndrome.

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.

VIPoma

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.
