Cholecystokinin (CCK)-secreting neuroendocrine tumors (CCKomas) are very rare neuroendocrine tumors of the pancreas. CCKomas can present with persistent non-watery diarrhea, weight loss combined with more specific symptoms of gallbladder disease and duodenal ulcer disease. The diagnosis is based on elevated circulating CCK levels in the absence of elevated circulating gastrin concentrations.
