triad comprising intractable, sometimes fulminating atypical ulcers, extremely elevated gastic acidity, and gastrin secreting non beta islet cell tumors.
A disorder in which tumors of the pancreatic islet cells produce large amounts of gastrin (a hormone), leading to excess acid in the stomach and, possibly, a peptic ulcer (ulcer of the stomach or the upper part of the small intestine).
