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.
