The antrum showed minor changes of reactive gastropathy, with no inflammation, intestinal metaplasia, glandular atrophy, or neuroendocrine cell hyperplasia. Printed from Surgical Pathology Criteria: WHO 2010 has changed back to neuroendocrine cell from endocrine cell for these lesions, Endocrine cell hyperplasia and neoplasia are equivalent terms to those used below, Gastric carcinoids and neuroendocrine cell proliferations arise in three settings, Hyperplasia, dysplasia and neoplasia are not uncommon, Most carcinoids are <1 cm and are not aggressive, May not progress even if not resected, Without MEN1, generally only neuroendocrine cell hyperplasia is seen, With MEN1, may have neuroendocrine cell dysplasia and neoplasia, Such carcinoids may behave aggressively, Over half may invade deeply and metastasize, Types of neuroendocrine cell proliferations, Chromogranin and/or synaptophysin stains are necessary for evaluation of neuroendocrine cells, Scattered individually, primarily in the basal crypt epithelium, Linear or micronodular clusters of at least 5 cells, Micronodular clusters 150 microns in greatest dimension, At least 2 linear chains / mm or 1 micronodule / mm, Enlargement and fusion of five or more micronodules, >150 microns in greatest dimension, Microinfiltration of lamina propria, Nodule with formation of new stroma, Nodules 0.5 mm to 0.5 cm have been termed microcarcinoids, Gastric endocrine cell proliferations typically show features seen in other GI tract well differentiated endocrine proliferations, Occasional reports of scattered larger atypical nuclei, Trabecular, acinar, pseudo glandular architecture, Variable positivity for neuroendocrine markers, It has been proposed that type A and B hyperplasia and dysplasia may progress to carcinoid (Berna 2008, Annibale 2001), This is not universally accepted for hyperplastic lesions (Solicia 1995), It would appear that both merit followup, The behavior of carcinoids is dependent upon size, proliferation rate and the setting in which it arises (see, Well differentiated processes including carcinoids, Duodenum NOS and proximal jejunum, Ileum and distal jejunum The foveolar component and the glandular component in both gastric regions showed a hyperplastic appearance. Although few previous cases have reported autoimmune gastritis and its association with G-cell hyperplasia and hypergastrinemia,79 this is the first known report of endoscopic findings of AMAG associated with G-cell hyperplasia showing the full developmental spectrum of ECL cell proliferation from hyperplasia to dysplasia to neuroendocrine tumor. 2018 Aug.

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. Correspondence: Patrick Brown, DO ([emailprotected]). [36], Type 3 NETs represent 15% to 20% of all g-NETs. Autoimmune metaplastic atrophic gastritis (AMAG) is a chronic inflammatory disease characterized by immune-mediated replacement of gastric parietal cells with atrophic and metaplastic mucosa.1 Patients with AMAG often present with dyspepsia or symptomatic anemia; however, many remain asymptomatic in the early stages of the disease. Liver metastases in prostate carcinoma: clinical characteristics and outcome. [Epithelial gastric polyps in a series of 13000 gastroscopies]. In these circumstances, we concluded that the tumor represented a type 3 gastric NET, detected in an advanced, metastatic stage. Hematol Oncol Clin N Am 2016;30:2148. When serum gastrin levels are >1,000 pg/mL, Zollinger-Ellison syndrome is often the first diagnosis to be suspected; however, keeping G-cell hyperplasia on the differential diagnosis is important to avoid subjecting these patients to unnecessary surgical procedures.
