In this article we reported a female patient with type 1 gastric neuroendocrine tumor (NET). Gastroscopy showed the presence of multiple polyp-like lesions sized 0.2–1.5 cm in the fundus and body of stomach. The main clinical manifestations were belching and fullness after a meal. She had a history of autoimmune atrophic gastritis and laboratory tests showed increased serum gastrin and acid deficiency, which met the diagnostic criteria of type 1 gastric NET. Treatments included endoscopic resection, sandostatin, and traditional Chinese herbs, and no relapse was noted during follow-up visits. The patient also had rectal NET. By analyzing this case, we tried to explore the diagnostic algorithm and clinical typing of type 1 gastric NET; meanwhile, along with literature review, we described the relapse rate of this disease and the value of regular follow-up (every 6–12 months). Finally, we analyzed the value of somatostatin analogue (SSA) in treating multiple type 1 gastric NET and in this case we demonstrated that SSA was effective in dissolving NET.
