The gastrointestinal tract has different types of endocrine cells that vary from 1 site to another, depending of the functional needs of each region. A possible explanation for this behavior could be the persistence of ectopic gastrin cells in atrophic corporeal mucosa and hypergastrinemia which promotes tumor growth.

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. A 16/13 mm lesion was detected at the level of the head of the pancreas, in close contact with duodenal wall. The work cannot be changed in any way or used commercially without permission from the journal. One review article suggests that surveillance every 612 months with endoscopic mucosal resection is sufficient for tumors less than 2 cm vs surgical antrectomy for larger or progressive tumors; however, data are limited on the optimal management of microneuroendocrine tumors.2 Some options to consider include EGD with EUS as was performed for our patient or potentially using virtual chromoendoscopy, an imaging technique that evolving research has shown to be beneficial in identifying and classifying neuroendocrine tumors.12,13.
