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. 2007 Spring;18(1):16-22. Current concepts on gastric carcinoid tumors. Yao JC, Hassan M, Phan A, et al. These NENs can be preceded by ECL cells hyperplastic and dysplastic lesions, whose oncologic potential has not yet been fully elucidated.

[3335] The endoscopic appearance of gastric tumors is similar with type 1 g-NETs, consisting of multiple small nodular lesions in the gastric body and fundus, but the surrounding mucosa is hypertrophic and various types of hyperplastic ECL cells proliferation can be found. PMC Neuroendocrine immunohistochemistry highlighted the neuroendocrine cell hyperplasia. Autoimmune diseases in autoimmune atrophic gastritis. [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. The fragments from the surrounding mucosa displayed histological features corresponding with an autoimmune atrophic gastritis (type A), limited to the corporeal region, with extensive intestinal and pseudopyloric metaplasia. [16], Some research focused on risk related to ECL cells changes, but it is difficult to define which type of proliferation has the greatest potential for neoplastic transformation.

[33], The patient with antral tumor and liver metastases (case 3) declined surgical treatment and chose the medical therapy. 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. [3]. Surgical treatment is recommended for patients with type 2 g-NETs, primarily directed to underlying disease (removal of gastrinomas, in order to reduce the ECL cells stimulation).

Primary location was lung (40.57%, n=43), folowed by pancreas (16.04%, n=17), stomach (15.09%, n=16), appendix (8.49%, n=9), small . 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. Rectal neuroendocrine tumors are increasingly being diagnosed since the implementation of screening colonoscopy in 2000. Biopsies were obtained from the largest gastric tumor and the surrounding mucosa. After using Caduet tablets, approximately 2% of patients experience dizziness, asthenia, abdominal . The patient did not consent for surgical treatment of the tumor, and oncologic therapy was indicated. World J Gastroenterol 2014;20:11825. During Caduet drug therapy, a variety of unwanted effects may arise, among which the most common is peripheral edema. Tumors occur in normal (nonatrophic) mucosa, without ECL cells proliferations. Atrophic body gastritis patients with enterochromaffin-like cell dysplasia are at increased risk for the development of type I gastric carcinoid. [2]. 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. Biopsies from surrounding mucosa show atrophic gastritis and hyperplasia of ECL cells. Bordi C, Azzoni C, D'Adda T, Caruana P, Carlinfante G. Pathologe.
