| Zollinger-Ellison s. |
a triad comprising (1) intractable, sometimes fulminating, and in many ways atypical peptic ulcers; (2) extreme gastric hyperacidity; and (3) gastrin-secreting, nonbeta islet cell tumors of the pancreas, which may be single or multiple, small or large, benign or malignant. The gastrinoma sometimes occurs in sites (e.g., the duodenum) other than the pancreas. See also multiple endocrine neoplasia, type I.
