The patient was diagnosed with AMAG based on her histologic and laboratory findings, although it remained unclear when she initially developed this condition. [51] Pancreaticoduodenectomy with total gastrectomy were performed in patient with type 2 gastric NET (case 2). Cases 1 and 3 had single hyperplastic polyps, while case 2 had three polyps. Thus, 3 types of tumors are recognized: type 1 associated with autoimmune chronic atrophic gastritis (A-CAG), type 2 associated with multiple endocrine neoplasia type 1 (MEN-1) and Zollinger Ellison syndrome (ZES), and type 3 sporadic.[12]. The changing face of chronic autoimmune atrophic gastritis: An updated comprehensive perspective. Gastrointestinal neuroendocrine tumors are diagnosed and staged by endoscopy with biopsy, endoscopic ultrasound, serology of biomarkers, imaging studies and functional somatostatin scans.

Gastroenteropancreatic neuroendocrine tumours: the current incidence and staging based on the WHO and European Neuroendocrine Tumour Society classification: an analysis based on prospectively collected parameters. The surrounding mucosa was hypertrophic, with different type of ECL cell proliferation, including linear, nodular and dysplastic lesions in the antrum as well as in the corpus, without metaplastic changes or glandular atrophy. Solitary type 3 g-NETs arising in normal mucosa may have an aggressive behavior, requiring a radical surgical therapy. In this case, our patient with diabetes, autoimmune thyroiditis, and pernicious anemia was found to have positive antigastric parietal cell and anti-intrinsic factor antibodies with gastric biopsy findings consistent with AMAG. 2018;89(8-S):1003. Hum Pathol 2013;44:182737. Tumors characterized by more than 20 mitoses/10 HPF, and a Ki-67 proliferative index >20% represent NECs. Disclaimer, National Library of Medicine Miyazaki Y, Shinomura Y, Murayama Y, et al. Four types of g-NENs have been described, based on the histopathological assessment of the number of mitoses per 10 HPF and the proliferative activity (Ki-67 index). Please try after some time. Two of the patients presented with epigastric pain and the other with fatigue from anaemia, and on endoscopy, all three were found to have superficially ulcerated gastric polyps in the body (cases 1 and 2) and fundus (case 3).

Li QL, Zhang YQ, Chen WF, Xu MD, Zhong YS, Ma LL, Qin WZ, Hu JW, Cai MY, Yao LQ, Zhou PH. A possible explanation for this behavior could be the persistence of ectopic gastrin cells in atrophic corporeal mucosa and hypergastrinemia which promotes tumor growth. 2007 Spring;18(1):16-22.

Gastrointestinal neuroendocrine tumors are rare slow-growing tumors with distinct histological, biological, and clinical characteristics that have increased in incidence and prevalence within the last few decades. [3]. 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 A prospective study of gastric carcinoids and enterochromaffin-like cell changes in multiple endocrine neoplasia type 1 and Zollinger-Ellison syndrome: identification of risk factors.
