ENETS consensus guidelines for the management of patients with digestive neuroendocrine neoplasms: functional pancreatic endocrine tumor syndromes. This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production. If these tests have identified lung cancer, more tests should be performed to clarify to what extent the cancer has spread. The excess gastrin binds to enterochromaffin-like cells causing hyperplasia, which may progress to dysplasia and rarely to gastric neuroendocrine tumors. Cancer 2015;121:58997.

Endocrine precursor lesions of gastroenteropancreatic neuroendocrine tumors. Microscopic examination of the largest gastric tumor revealed a neuroendocrine neoplasm invading the mucosa and submucosa, reaching the muscularis propria. 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. 1990 Jun;14(6):503-13. Carcinoid syndrome generally occurs when jejuno-ileal neuroendocrine tumors metastasize to the liver. [31].

Patients with small intestinal neuroendrocrine tumors frequently show clinical symptoms and develop distant metastases more often than those with neuroendocrine tumors of other organs. They contain chromogranin A, synaptophysin and neuron-specific enolase which are necessary for making a diagnosis of neuroendocrine tumor. noma, neuroendocrine carcinomas, and small cell Barrett's esophagus and adenocarcinoma remain carcinoma, also occur .

Written informed consent was obtained from each patient before enrollment. [38]. [9], Gastric NENs were classified using the 2010 WHO classification of digestive NENs, which consists of a grading system, independently of the immunoprofile of the proliferating cells: grade 1 neuroendocrine tumors (G1 NETs), grade 2 neuroendocrine tumors (G2 NETs), G3 neuroendocrine carcinomas (NECs), and mixed adenoneuroendocrine carcinomas.

However, in another patient treated by antrectomy, postoperatively gastrin levels remained higher than normal, and NET recurrence was reported 5 years after the antrectomy. 2007 Fall;18(3):150-5. [18] Severe linear hyperplasia represents a predictive factor for type 2 gastric NET development in patients with MEN-1 syndrome, according to data reported by Berna et al.

Thus, for patients with atrophic gastritis and associated G-cell hyperplasia, consideration should be given to evaluate with interval surveillance endoscopy with gastric mapping biopsies to assess for gastric intestinal metaplasia and stomach cancer. [3335] The endoscopic appearance of gastric tumors is similar with type 1 g-NETs, consisting of multiple small nodular lesions in the gastric body and fundus, but the surrounding mucosa is hypertrophic and various types of hyperplastic ECL cells proliferation can be found. This case exemplifies a thorough diagnostic workup for AMAG with GNET and reviews the pathophysiology behind the development of this condition. 2007 Dec;36(4):851-65.

Endocrine cells in the GI tract consist of less than 1% of the mucosa; are normally distributed at the surface or base of glandular epithelial cells, such as in the gastric pits of the stomach and the crypts of the small intestine and colorectum; and contain secretory . We present a case of AMAG in a patient with dyspepsia who was diagnosed with G-cell hyperplasia with progression to type 1 gastric microneuroendocrine tumor. Bookshelf Given concern for type 1 GNET, she underwent a gallium-68 DOTATATE positron emission tomography scan, which was negative. Random biopsies were obtained of the gastric antrum and body with immunohistochemistry demonstrating G cells by (A) gastrin immunostaining, (B) positive synaptophysin present in aggregates measuring up to 0.9 mm, and (C) Ki-67 proliferation index of less than 3% within these aggregates with MIB1 staining. [10], In 2017, a new WHO classification divided NENs in 3 types of well differentiated NETs (G1 NETs present <2 mitoses/10 HPF, Ki-67 index <3%; G2 NETs present 2 to 20 mitoses/10 HPF, and a Ki-67 index between 3% and 20%; grade 3 neuroendocrine tumors (G3 NETs) present more than 20 mitoses/10 HPF, and a Ki-67 proliferative index >20%), and 2 types of poorly differentiated NECs (small-cell type and large-cell type, with more than 20 mitoses/10 HPF, and a Ki-67 proliferative index >20%). 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. Am J Surg Pathol. [4147] A gastrin/cholecystokinin 2 receptor antagonist, Netazepide, showed promising results, by decreasing the number and the size of the tumors and by normalizing CgA levels.[48]. Autoimmune gastritis: Pathologist's viewpoint. [24]. Ultrasound-guided liver biopsy confirmed liver metastases from the neuroendocrine tumor, with positive synaptophysin and chromogranin on immunohistochemistry (Fig. [11,12], In contrast with most of the digestive NENs, gastric tumors may have a specific clinical context, with distinct prognosis and therapeutic management.

After 6 months, the patient underwent surveillance EGD, and random biopsies were assessed with immunohistochemistry. This review provides simple, yet rigorous guidelines on how to recognize, classify, and diagnose the neuroendocrine proliferations found in the stomach, emphasizing the most common background in which they arise, atrophic gastritis.
