Zollinger-Ellison Syndrome: Tumor Distribution Sites
Zollinger-Ellison syndrome (ZES) is characterized by tumors called gastrinomas, which excessively produce the hormone gastrin. This leads to high levels of stomach acid and severe peptic ulcers.
Gastrinoma Locations
While gastrinomas most frequently arise in the pancreas (around 40-50% of cases), a significant number occur outside this organ. Understanding these non-pancreatic sites is crucial for diagnosis and treatment.
Common Non-Pancreatic Site
Among the non-pancreatic locations, the duodenum is the most common site for gastrinoma development in Zollinger-Ellison syndrome. While the stomach itself can be affected by the acid hypersecretion, the primary tumor (gastrinoma) is less commonly found there compared to the duodenum.
Therefore, the most common non-pancreatic site for tumour distribution in Zollinger-Ellison syndrome is the duodenum.
