Water-Clear Cell Hyperplasia. Online ahead of print. 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. 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. Gastrointestinal neuroendocrine neoplasms (NENs) represent a heterogeneous group of neoplasms originating from endocrine cells that are located in the gastrointestinal tract.

Endoscopic submucosal dissection for foregut neuroendocrine tumors: an initial study. Thus, for patients with atrophic gastritis and associated G-cell hyperplasia, consideration should be given to evaluate with interval surveillance endoscopy with gastric mapping biopsies to assess for gastric intestinal metaplasia and stomach cancer. By immunohistochemistry, biopsies demonstrated G-cells by gastrin immunostaining, confirming antral-type mucosal origin. MeSH 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.

When serum gastrin levels are >1,000 pg/mL, Zollinger-Ellison syndrome is often the first diagnosis to be suspected; however, keeping G-cell hyperplasia on the differential diagnosis is important to avoid subjecting these patients to unnecessary surgical procedures. 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).

Two of the patients presented with epigastric pain and the other with fatigue from anaemia, and on endoscopy, all three were found to have superficially ulcerated gastric polyps in the body (cases 1 and 2) and fundus (case 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).
