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. Praxis (Bern 1994). -, Am J Surg Pathol. [25,26] The histological evaluation shows well-differentiated cells, growing in trabecular patterns, usually confined to mucosa or submucosa, immunoreactive for chromogranin A and synaptophysin, vesicular monoamine transporter 2, and somatostatin receptor 2A. [40], Regarding the therapeutic approach, annual or twice yearly endoscopic surveillance for small tumors (<10 mm diameter), surgical therapy (antrectomy, gastrectomy), endoscopic therapy (polypectomy, endoscopic mucosal resection or endoscopic submucosal dissection) for tumors >10 mm diameter, long-acting somatostatin analogs lanreotide and octreotide, are available options for type 1 g-NETs.

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). Close communication between the histopathologist and clinician is required, with an analysis of the relevant clinical data, correlated with histologic analysis of tumor and nontumor tissue. 2020;59(6):799803. Solitary type 3 g-NETs arising in normal mucosa may have an aggressive behavior, requiring a radical surgical therapy. Accessibility In addition, there may be multiple ECL (argyrophil neuroendocrine) tumours (carcinoids) which are often of considerable size, but only rarely show metastases [ 15].

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 Available from.

One review article suggests that surveillance every 612 months with endoscopic mucosal resection is sufficient for tumors less than 2 cm vs surgical antrectomy for larger or progressive tumors; however, data are limited on the optimal management of microneuroendocrine tumors.2 Some options to consider include EGD with EUS as was performed for our patient or potentially using virtual chromoendoscopy, an imaging technique that evolving research has shown to be beneficial in identifying and classifying neuroendocrine tumors.12,13. 30100 Telegraph Road, Suite 408, Bingham Farms, Michigan 48025 (USA) enterochromaffin-like-cells; gastric; immunostaining; mitoses; neuroendocrine; proliferative index.
