[18] Severe linear hyperplasia represents a predictive factor for type 2 gastric NET development in patients with MEN-1 syndrome, according to data reported by Berna et al. 1 Introduction. 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. At increased levels, gastrin binds to ECL cells through the cholecystokinin-2 receptor and causes ECL cell hyperplasia,1 which may progress to dysplasia and type 1 GNET, occurring in 1%12.5% of cases.6 Furthermore, it has been reported that AMAG and type 1 GNET can occur with or without the presence of other autoimmune diseases including type 1 diabetes mellitus, autoimmune thyroiditis, and pernicious anemia, as seen in our patient.11 The current medical literature does not routinely recommend surveillance endoscopy for patients with AMAG. [20,21] Each marker has a different specificity and sensitivity.

Vannella L, Sbrozzi-Vanni A, Lahner E, et al. Autoimmune metaplastic atrophic gastritis (AMAG) is a chronic inflammatory disease characterized by immune-mediated replacement of gastric parietal cells with atrophic and metaplastic mucosa.1 Patients with AMAG often present with dyspepsia or symptomatic anemia; however, many remain asymptomatic in the early stages of the disease. Whether drugs that can elevate serum gastrin levels, such as proton pump inhibitors (PPIs), can produce the same tissue effect is not . Ann Surg. We present a case of AMAG in a patient with dyspepsia who was diagnosed with G-cell hyperplasia with progression to type 1 gastric microneuroendocrine tumor. 1989 Mar 1;63(5):881-90.

Rare cases of G 2 type 3 NETs (solitary, developed in the absence of hypergastrinemia) with liver metastasis or ovarian metastasis were previously reported.[57,58]. G-cells are located at the base of mucous neck cells and in the superficial mucous gland cells. Macroscopic evaluation of the resected specimen showed multiple nodular lesions in the stomach, protruding from the mucosa, with dimensions between 10 and 60 mm, distributed in the gastric body. [19], Although ECL cells are not readily recognized on routine hematoxylin and eosin staining, they contain vesicular granules highlighted with immunohistochemical staining. Cai YC, Banner B, Glickman J, Odze RD. [34]. . Histopathology 2007;50:3041. Fluid retention occurs in about 10% of patients using Caduet. EGD showed diffuse moderate inflammation, and biopsies from the gastric antrum demonstrated G-cell hyperplasia, again highlighted by gastrin immunostaining (Figure 3).

WHO classification of digestive NENs was adopted in 2010. 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).

The histopathological evaluation of the polypectomy specimen revealed a nodular tumor of 10 mm diameter, with typical neuroendocrine features invading the mucosa, and with minimal extension in the submucosa. [9], Gastric NENs were classified using the 2010 WHO classification of digestive NENs, which consists of a grading system, independently of the immunoprofile of the proliferating cells: grade 1 neuroendocrine tumors (G1 NETs), grade 2 neuroendocrine tumors (G2 NETs), G3 neuroendocrine carcinomas (NECs), and mixed adenoneuroendocrine carcinomas.

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. Tumors occur in normal (nonatrophic) mucosa, without ECL cells proliferations. Neuroendocrine cell proliferations of the stomach arise in various settings and show features ranging from hyperplasia to neoplasia; . Serum chromogranin A is the most commonly used biomarker to assess the bulk of disease and monitor treatment and is raised in both functioning and non-functioning neuroendocrine tumors. No embolies were identified and necrosis was not present. The epidemiology of neuroendocrine tumors in Taiwan: a nation-wide cancer registry-based study. Scherulb H, Cadiot G, Jensen RT, Rosch T, Stolzel U, Kloppel G. Neuroendocrine tumors of the stomach (gastric carcinoids) are on rise, small tumors, small problems? Some authors advocate antrectomy in order to eliminate the gastrin stimulus that promotes tumor growth, and local resection of the largest tumors with subsequent endoscopic surveillance of the gastric remnant. [52] In the case of metastatic liver disease, surgery, somatostatin analogues, chemotherapy (streptozocin, 5-fluorouracil with leucovorin, cyclophosphamide, doxorubicin, oxaplatin, dacarbazine), and locoregional control methods (targeted radionucleotide therapies, transarterial chemoembolization, radiofrequency ablation) are recommended. Autoimmune metaplastic atrophic gastritis is caused by immune-mediated destruction of gastric parietal cells. Patients with colonic neuroendocrine tumors may present with pain, bleeding, altered bowel habits, weight loss, anorexia or even bowel obstruction ( Best Pract Res Clin Gastroenterol 2012;26:775 ) Carcinoid syndrome occurs in patients with liver metastasis. In many cases, tumors remain asymptomatic and may be diagnosed as incidental findings during upper gastrointestinal endoscopy. Online ahead of print. Cases 1 and 3 had single hyperplastic polyps, while case 2 had three polyps. Additional workup revealed elevated chromogranin-A of 211 ng/mL, positive glutamic acid decarboxylase antibodies >120 IU/mL, positive gastric parietal cell antibody of 46.9 units, and positive intrinsic factor antibodies. Positive immunohistochemical staining for chromogranin proved neuroendocrine nature of gastric tumor and liver metastases. The common feature and causal link is atrophic gastritis, which predisposed the gastric mucosa to the development of both neuroendocrine cell hyperplasia and tumours, and hyperplastic polyps. Am J Surg Pathol. This website is intended for pathologists and laboratory personnel but not for patients. [44]. The WHO grading system divides stomach NETs in 3 groups: grade 1 (neuroendocrine tumour G1 or WHO 1) grade 2 (neuroendocrine tumour G2 or WHO 2) grade 3 (neuroendocrine carcinoma G3 or WHO 3) The grade of a stomach NET is based on how quickly the cells are dividing. 2010 Nov;34(11):1591-8 The pancreatic tumor was a well-differentiated NET, with uniform cells, without nuclear pleomorphism, with Ki-67 proliferative index <2%, and 1 mitosis/10 HPF.

The classic carcinoid syndrome consisting in cutaneous flushing, tachycardia and secretory diarrhea rarely occurs, but is observed most frequently in patients with liver metastases. 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. 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. 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. 1 5th edLyon: IARC Press; 2019. 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. Laboratory evaluation showed elevated fasting serum gastrin levels (1350 pg/mL), as well as serum antibodies to gastric parietal cells. Cancer 2015;121:58997.
