Our case series emphasized the role of close collaboration between clinician and pathologist, as well as the importance of a detailed pathology report. 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 Diagnosis and treatment of gastric neuroendocrine tumours. 2007 Spring;18(1):16-22.

In all cases, the neuroendocrine component was present within and between the hyperplastic foveolar glands of the polyps and overall formed the minor part of the polyps. Tumors were limited to the superficial part of the submucosa, without lymph node involvement. 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. 2021;53(6):E2156.

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]. [24], Gastric NENs (g-NENs) are rare tumors and represent 5% to 23% from all gastrointestinal NENs, according to the published data. [50].

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. Available from. G1 NETs are tumors presenting <2 mitoses/10 HPF, with a Ki-67 index <2%. 9.

The behavior of type 1 g-NETs is typically indolent, although a few cases of aggressive tumors (G3 NET) have been described. Endoscopic treatment (endoscopic mucosal resection or endoscopic submucosal dissection) was indicated in small (<20 mm diameters) G1 or G2 tumors, with no lymph node or distant metastases. 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. modify the keyword list to augment your search.
