We present a rare case of autoimmune metaplastic atrophic gastritis associated with G-cell hyperplasia showing the full developmental spectrum of enterochromaffin-like cell proliferation from hyperplasia to dysplasia to neuroendocrine tumor. 2 Previous studies have reported an annual incidence of type 1 GNET ranging from 0.4% to 0.68% in patients with AMAG. Br J Clin Pharmacol 2017;83:46675. 8600 Rockville Pike . In the setting of hypergastrinemia, duodenal ulcers, neuroendocrine gastric tumors and hypertrophic gastric mucosa, we suspected a ZollingerEllison syndrome. Cancers (Basel). Unusually aggressive type 1 gastric carcinoid: a case report with a review of the literature. 1993;32(7):6026. A 39-year-old woman with pernicious anemia and a gastric mass. In the head of the pancreas, a small nodule, well-demarcated, grey tan, of 25 mm in size, was identified. [17] In our patient with CAG and type 1 g-NET, endoscopic resection of the largest tumor and endoscopic surveillance were recommended (case 1). Immunohistochemical staining for CDX-2, PDX-1, NESP-55, and TTF-1 can help distinguish gastrointestinal carcinoid tumors from pancreatic endocrine and pulmonary carcinoid tumors.

In type 3 g-NET, detected in metastatic stage, oncologic therapy was performed. Antral and corporeal biopsies, in addition to biopsies from the tumors, are important to be obtained, in order to determine the type of the tumor. The cytomorphology of carcinoid tumor (low-grade neuroendocrine carcinoma) is similar to that of the tumor at different sites. 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. Autoimmune diseases in autoimmune atrophic gastritis. 2001 Apr;25(4):500-7 It is unclear whether the two pathologies occurred simultaneously or independently. This case exemplifies a thorough diagnostic workup for AMAG with GNET and reviews the pathophysiology behind the development of this condition.

Current concepts on gastric carcinoid tumors. At the level of duodenum, multiple ulcers were found (Fig. Tumors develop as multiple polypoid lesions, usually small (<10 mm), in the corpus of the stomach or in the gastric fundus. World J Clin Cases. As such, articles are written and edited by countless contributing members over a period of time. Microscopic examination of the largest gastric tumor revealed a neuroendocrine neoplasm invading the mucosa and submucosa, reaching the muscularis propria.

Gastric neuroendocrine neoplasms: A review. Metastases may occur in 10% to 30% of patients. Random biopsies were obtained in the gastric antrum with immunohistochemistry redemonstrating G-cell hyperplasia highlighted by (A) gastrin immunostaining. However, our patient had AMAG with G-cell hyperplasia that had progressed to type 1 GNET, thereby increasing the risk of developing metastatic disease. 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.

Bethesda, MD 20894, Web Policies The efficacy of endoscopic submucosal dissection of type I gastric carcinoid tumors compared with conventional endoscopic mucosal resection. Type 2 NETs are also well-differentiated tumors, confined to mucosa and submucosa in the majority of cases. Wolters Kluwer Health, Inc. and/or its subsidiaries. Data is temporarily unavailable. Neuroendocrine proliferations of the stomach: a pragmatic approach for the perplexed pathologist. 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. [9]. 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). Usefulness of laparoscope-assisted antrectomy for gastric carcinoids with hypergastrinemia. [11]. Exploring the rising incidence of neuroendocrine tumors: a population-based analysis of epidemiology, metastatic presentation, and out-comes. 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). This leads to the absence of gastric acid production causing compensatory hyperplasia of gastric antral G-cells with hypergastrinemia.10 Furthermore, there is potentially decreased inhibition from gastric D-cells, contributing to increased gastrin production. Articles are a collaborative effort to provide a single canonical page on all topics relevant to the practice of radiology.

Consequently, these lesions tend to remain widely underdiagnosed until they progress to easily recognizable neuroendocrine tumors. sharing sensitive information, make sure youre on a federal [28]. [4]. [10] The classification system was updated in 2017 and 2018, and NENs were divided in neuroendocrine tumors (NETs), NECs, and mixed neuroendocrinenon-neuroendocrine neoplasms (MiNENs). Surgical Pathology Criteria The clinical presentations, as well as pathological features, represent important data in establishing the type of the tumor, in estimating the tumor behavior, and in selecting the best therapeutic strategy. Hum Pathol 2011;42:137384. The immunohistochemical examination with chromogranin A and synaptophysin highlighted also a linear and nodular hyperplasia of endocrine cell only in the corpus. The prognosis was good in case 1, whilst poorer outcomes were associated with more aggressive tumors in case 2 and case 3. g-NENs are rare tumors with distinct clinical and histological features.

The unique aspect of this case consists of the presence of a previously treated prostatic malignancy, with an apparently good outcome in the absence of lymph nodes and bone metastasis, and the subsequent detection of an advanced metastatic disease. [37]. The patients follow-up was selected according to tumor behavior, from regular endoscopic surveillance to oncology follow-up. Coati I, Fassan M, Farinati F, Graham DY, Genta RM, Rugge M. World J Gastroenterol. [13]. No metastases were detected in the 12 peripancreatic and 16 perigastric lymph nodes. 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. Epub 2013 May 2. In the perigastric adipose tissue 16 lymph nodes were found, the largest with 10 mm diameter. -, Am J Surg Pathol. United European Gastroenterol J 2020;8:1407. WHO International Histological Classification of Tumours 2nd edBerlin: Springer; 2000. Focal nodular hyperplasia (n = 3; mean size 8.0 mm) tended to occur in a younger age group (mean age 40.3 years; p less than 0.001). 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.
