MIB1 immunohistochemical stain showed a Ki-67 proliferation index of less than 3% within these aggregates, which was pathologically suggestive of a type 1 microneuroendocrine tumor (Figure 2). Poorly differentiated features, tumoral necrosis, Tumors with neuroendocrine (tumor or carcinoma) and adenocarcinoma components of 30% each, Some use size criteria < 5 mm as a definition for hyperplasia and > 5 mm is the minimum size necessary to diagnose a NET, Some may diagnose NET when grossly there is a polyp / nodule regardless of size in the absence of other explanatory findings, Other criteria have been proposed for microscopic proliferations: if there is nodular growth of ECL cells > 150 microns or if there is a conglomeration of nodules, signs of microinfiltration or new stroma, then the lesion has been proposed to be classified as dysplasia or Tis, Ki67 and mitotic figure count, whichever is higher, Ki67 and mitotic figure count, whichever is lower.

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. No embolies were identified and necrosis was not present. Non-hyperplastic adjacent mucosa showed less prominent neuroendocrine cell hyperplasia. to the first signs and symptoms of the disorder preceding a psychotic episode can lead us towards a diagnostic and can outline . 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. [11], The most recent WHO classification system[12] divided g-NENs in well differentiated NETs, poorly differentiated NECs (small cell and large cell), and MiNENs. The antrum contains gastrin secreting cells or G-cells. Well differentiated neuroendocrine pattern: Monotonous regular cells with round or oval nuclei with salt and pepper chromatin and moderate eosinophilic granular cytoplasm, Organoid architecture: tumor cells arranged in nests, trabecular or insular pattern (, In some cases, nuclear pleomorphism may be encountered (endocrine atypia) but is not associated with tumor aggressiveness (. enterochromaffin-like-cells; gastric; immunostaining; mitoses; neuroendocrine; proliferative index. Laboratory evaluation showed elevated fasting serum gastrin levels (1350 pg/mL), as well as serum antibodies to gastric parietal cells. The first patient was a 41-year-old female with weight loss, persistent dyspeptic complaints and a history of pernicious anemia. Endocr Pathol 2021;32:51723. Medicine.

HE = hematoxylineosin stain, NBI = narrow-band imaging. Cases 1 and 3 had single hyperplastic polyps, while case 2 had three polyps. [58] Although up to 5 neuroendocrine cell types have been described in human gastric mucosa, most g-NENs are composed of nonfunctioning ECL (enterochromaffin-like) cells.

Histopathological and laboratory evaluation, together with imagistic evaluation (abdominal ultrasound, endoscopic ultrasound, and magnetic resonance imaging) allowed the distinction between 3 different types of gastric tumors: type 1 enterochromaffin-like-cell G1 NET, type 2 enterochromaffin-like-cell G2 NET, and type 3 G2 NET with liver metastases. Gastrointestinal neuroendocrine tumors are diagnosed and staged by endoscopy with biopsy, endoscopic ultrasound, serology of biomarkers, imaging studies and functional somatostatin scans. Pancreatic Neuroendocrine Neoplasms : General. It is a non-progressive disease of the interstitial tissues of the lungs.

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.
