View source for Zollinger-Ellison syndrome

'''Zollinger-Ellison syndrome''' is a rare cause of [[peptic ulcer disease]]. It is characterized by multiple peptic ulcerations in the stomach, duodenum and even jejunum. It is caused by neuroendocrine tumors that produce gastrin, called [[Gastrinoma|gastrinomas]], and they are often located in the pancreas, duodenum or the lymph nodes of the abdomen. Increased gastrin means increased stomach acid.
