The antrum contains gastrin secreting cells or G-cells. ScientificWorldJournal. The common feature and causal link is atrophic gastritis, which predisposed the gastric mucosa to the development of both neuroendocrine cell hyperplasia and tumours, and hyperplastic polyps. The gastrointestinal tract has different types of endocrine cells that vary from 1 site to another, depending of the functional needs of each region. Antral and corporeal biopsies, in addition to biopsies from the tumors, are important to be obtained, in order to determine the type of the tumor. Neuroendocrinology 2004;80: (Suppl 1): 125. Organ Pathology (Turton J, Hooson J, eds). [17]. Endoscopic polypectomy of the largest tumor (10 mm diameter) was performed, and targeted biopsies from the other polypoid lesions and from the surrounding mucosa were obtained, including distinct fragments from the antrum and corpus.

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.

Immunohistochemical markers of endocrine differentiation are used to highlight normal and neoplastic cells, and they can be divided into 4 classes: cytosolic or cell membrane markers (most common neuron specific enolase or NSE and more recently vesicular monoamine transporter-2), small vesicle associated markers (most common synaptophysin), secretory granule associated (including chromogranin A), and specific peptide hormone markers (such as serotonin, somatostatin, and gastrin).
