This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production.

Microscopic examination of the biopsy fragments revealed a neuroendocrine type proliferation, without significant nuclear pleomorphism or necrosis. At increased levels, gastrin binds to ECL cells through the cholecystokinin-2 receptor and causes ECL cell hyperplasia,1 which may progress to dysplasia and type 1 GNET, occurring in 1%12.5% of cases.6 Furthermore, it has been reported that AMAG and type 1 GNET can occur with or without the presence of other autoimmune diseases including type 1 diabetes mellitus, autoimmune thyroiditis, and pernicious anemia, as seen in our patient.11 The current medical literature does not routinely recommend surveillance endoscopy for patients with AMAG.

ECL cells proliferation may occur in patients with corporeal atrophic gastritis, in patients with MEN-1 syndrome, or in patients with hypo/aclorhydria induced by long-standing proton pump inhibitor therapy. Immunohistochemical markers of endocrine differentiation are used to highlight normal and neoplastic cells, and they can be divided into 4 classes: cytosolic or cell membrane markers (most common neuron specific enolase or NSE and more recently vesicular monoamine transporter-2), small vesicle associated markers (most common synaptophysin), secretory granule associated (including chromogranin A), and specific peptide hormone markers (such as serotonin, somatostatin, and gastrin).
