Distinct subtypes of NETs are defined: histamine-producing ECL cell NET (Type 1 and Type 2); Type 3 NET (G1 NET, G2 NET, and G3 NET); somatostatin-producing D-cell NET; gastrin-producing G-cell NET; serotonin-producing enterochromaffin-cell NET.[22]. 7. generally only neuroendocrine cell hyperplasia is seen; With MEN1, may have neuroendocrine cell dysplasia and neoplasia . The excess gastrin binds to enterochromaffin-like cells causing hyperplasia, which may progress to dysplasia and rarely to gastric neuroendocrine tumors. Online ahead of print. The foveolar component and the glandular component in both gastric regions showed a hyperplastic appearance. Non-hyperplastic adjacent mucosa showed less prominent neuroendocrine cell hyperplasia. Biopsies from surrounding mucosa show atrophic gastritis and hyperplasia of ECL cells. Best Pract Res Clin Gastroenterol 2012;26:71935. 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.
