Tumors occur in normal (nonatrophic) mucosa, without ECL cells proliferations. Autoimmune metaplastic atrophic gastritis (AMAG) is a chronic inflammatory disease characterized by immune-mediated replacement of gastric parietal cells with atrophic and metaplastic mucosa.1 Patients with AMAG often present with dyspepsia or symptomatic anemia; however, many remain asymptomatic in the early stages of the disease. [21]. She was subsequently diagnosed with a type 1 microneuroendocrine tumor with reconfirmation of AMAG and G-cell hyperplasia, and she is currently undergoing surveillance endoscopy for cancer progression.

Gastric neuroendocrine tumors arise from enterochromaffin like cells. 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.
