Laparoscopic antrectomy for the treatment of type I gastric carcinoid tumors. 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 [50] Octreotide showed good results in tumors regression in ZES or MEN-1.

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. [30]. The features are consistent with autoimmune gastritis in the appropriate clinical context. Liver metastases in prostate carcinoma: clinical characteristics and outcome. [21]. 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.

Hypergastrinemia represents the stimulus for hyperplastic proliferation of ECL cells and the development of NETs. [19], Although ECL cells are not readily recognized on routine hematoxylin and eosin staining, they contain vesicular granules highlighted with immunohistochemical staining. The classifications of neuroendocrine proliferations that lead from enterochromaffin-like cell hyperplasia to neuroendocrine tumors in the stomach are complicated and relatively inaccessible to nonspecialists. neuroendocrine tumor of pancreas pathology outlines.

[Autoimmune metaplastic atrophic gastritis, G cell hyperplasia and neuroendocrine tumor of stomach]. [10], In 2017, a new WHO classification divided NENs in 3 types of well differentiated NETs (G1 NETs present <2 mitoses/10 HPF, Ki-67 index <3%; G2 NETs present 2 to 20 mitoses/10 HPF, and a Ki-67 index between 3% and 20%; grade 3 neuroendocrine tumors (G3 NETs) present more than 20 mitoses/10 HPF, and a Ki-67 proliferative index >20%), and 2 types of poorly differentiated NECs (small-cell type and large-cell type, with more than 20 mitoses/10 HPF, and a Ki-67 proliferative index >20%). 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.

The changing face of chronic autoimmune atrophic gastritis: An updated comprehensive perspective. J Clin Endocrinol Metab. After a succinct outline of the types and distribution of the neuroendocrine cells in the normal gastric mucosa we discuss the most common situations in which the pathologist needs to think about gastric neuroendocrine cells. 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). After a literature search, we found that liver metastases secondary to prostatic adenocarcinoma are very uncommon, and usually occur in patients presenting a systemic aggressive disease with bone and/or lymph node metastases. One hundred years after carcinoid: epidemiology of and prognostic factors for neuroendocrine tumors in 35,825 cases in the United States. Proposed grading scale based on proliferation. 6B), synaptophysin, cluster of differentiation X2 (corresponding with a primary gastric lesion), and negative staining with cytokeratin 7 and 20, and for prostate-specific antigen. Meet the TRISH Team. to the first signs and symptoms of the disorder preceding a psychotic episode can lead us towards a diagnostic and can outline . 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. 6. Hypergastrinemia states such as achlorhydria from gastric mucosal atrophy or a gastrin-producing tumor in humans have been associated with the development of enterochromaffin-like (ECL) cell hyperplasia and gastric neuroendocrine tumors (GNETs). 1990 Jun;14(6):503-13.

A 2 cm polypoid lesion was detected in the antrum showing an irregular mucosal pattern on narrow-band imaging (Fig. In this case of type 2 ECL cell NET the surgical treatment was recommended, and pancreaticoduodenectomy with total gastrectomy were performed. [9]. Next, EGD with endoscopic ultrasound (EUS) of the gastrinoma triangle was performed. Gastrointestinal neuroendocrine neoplasms (NENs) represent a heterogeneous group of neoplasms originating from endocrine cells that are located in the gastrointestinal tract. Epub 2014 Aug 22.

Our case reports present clinical scenarios that may be encountered in practice, focusing on clinical and histopathological features of different types of g-NENs with their specific management. As a result, the marked hypergastrinemia was considered to have been caused by G-cell hyperplasia related to a block in the negative feedback mechanism of somatostatin against achlorhydria with autoimmune gastritis.

The excess gastrin binds to enterochromaffin-like cells causing hyperplasia, which may progress to dysplasia and rarely to gastric neuroendocrine tumors. Hematol Oncol Clin N Am 2016;30:2148. 5), while surrounding antral and corporeal mucosa showed normal mucosal and vascular patterns. Rodriguez-Castro KI, Franceschi M, Miraglia C, et al. 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.
