In addition, there may be multiple ECL (argyrophil neuroendocrine) tumours (carcinoids) which are often of considerable size, but only rarely show metastases [ 15]. When serum gastrin levels are >1,000 pg/mL, Zollinger-Ellison syndrome is often the first diagnosis to be suspected; however, keeping G-cell hyperplasia on the differential diagnosis is important to avoid subjecting these patients to unnecessary surgical procedures.
