[23,24] These are related to hypergastrinemia due to a compensatory hyperplasia of antral G cells, in response to hypo/achlorhydria induced by the loss of specialized glands in the body. 1989 Mar 1;63(5):881-90. All polyps showed linear neuroendocrine cell hyperplasia within hyperplastic foveolar epithelium both at the surface and within deeper-situated glands. In general practice gastric biopsy specimens are often numerically and topographically inadequate for the evaluation of atrophic gastritis; therefore, we have included an algorithm to address specifically the steps that should be taken when confronted with suboptimal sampling. [8]. patients were diagnosed with FGPs, 1.8% with hyperplastic polyps, 0.1% with gastric adenomas and 0.06% with type I neuroendocrine tumours (NETs). N Engl J Med 2000;343:5514.

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 Endoscopic polypectomy of the largest lesion was performed in patient with type 1 g-NET and autoimmune chronic atrophic gastritis, followed by regular endoscopic surveillance with biopsies. 2015;3(3):2018.

Small intestinal neuroendocrine tumor is the most common small bowel malignancy. [7]. Histopathological and laboratory evaluation, together with imagistic evaluation (abdominal ultrasound, endoscopic ultrasound, and magnetic resonance imaging) allowed the distinction between 3 different types of gastric tumors: type 1 enterochromaffin-like-cell G1 NET, type 2 enterochromaffin-like-cell G2 NET, and type 3 G2 NET with liver metastases. 2013 Sep;44(9):1827-37. doi: 10.1016/j.humpath.2013.02.005.

In the setting of hypergastrinemia, duodenal ulcers, neuroendocrine gastric tumors and hypertrophic gastric mucosa, we suspected a ZollingerEllison syndrome. Eur J Gastroenterol Hepatol 2012;24:58993. Given the oncogenic potential of ECL cells changes, a regular endoscopic and histological follow-up of the patient is advisable when ECL cells hyperplastic and dysplastic proliferations are detected in gastric biopsy specimens. doi: 10.1093/jscr/rjac582.
