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. La Rosa S, Vanoli A. Gastric neuroendocrine neoplasms and related precursor lesions.

Berna MJ, Annibale B, Marignani M, Luong TV, Corleto V, Pace A, Ito T, Liewehr D, Venzon DJ, Delle Fave G, Bordi C, Jensen RT. The patients follow-up was selected according to tumor behavior, from regular endoscopic surveillance to oncology follow-up. MIB1 immunohistochemical stain showed a Ki-67 proliferation index of less than 3% within these aggregates, which was pathologically suggestive of a type 1 microneuroendocrine tumor (Figure 2). Boyce M, Moore AR, Sagatun L, et al.

AMAG is associated with other autoimmune diseases and is a risk factor for the development of type 1 gastric neuroendocrine tumor (GNET).2 Previous studies have reported an annual incidence of type 1 GNET ranging from 0.4% to 0.68% in patients with AMAG.3,4 Lately, the incidence of AMAG and type 1 GNET has increased globally, partly owing to improved awareness of these diseases.5 Type 1 GNET comprises 70%80% of all GNETs and generally has an excellent prognosis after resection, with a metastatic potential between 2% and 5%.6 Despite the relatively benign course of type 1 GNET, careful consideration should be placed on diagnosis and management, given the increasing incidence of these tumors.
