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.

World J Clin Cases. 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.

EUS was grossly normal without findings of a primary tumor or mucosal abnormalities. Corporeal atrophic gastritis with multiple polypoid lesions on the greater curvature and on the anterior wall of the gastric body up to 10 mm in size was identified (Fig. 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.

[19], Although ECL cells are not readily recognized on routine hematoxylin and eosin staining, they contain vesicular granules highlighted with immunohistochemical staining. [48]. [20,21] Each marker has a different specificity and sensitivity. Author contributions: P. Brown and B. Tetali wrote the manuscript. Disclaimer, National Library of Medicine Bookshelf Considering the diversity of the endocrine population of cells and the hormonal complexity of the gastrointestinal system, it is surprising that the diseases of the system are so limited. Prostate carcinoma metastatic to the stomach: report of two cases and review of the literature. The classic carcinoid syndrome consisting in cutaneous flushing, tachycardia and secretory diarrhea rarely occurs, but is observed most frequently in patients with liver metastases. Solcia E, Fiocca R, Villani L, Luinetti O, Capella C. Hyperplastic, dysplastic, and neoplastic enterochromaffin-like-cell proliferations of the gastric mucosa. Endocrine cells in the GI tract consist of less than 1% of the mucosa; are normally distributed at the surface or base of glandular epithelial cells, such as in the gastric pits of the stomach and the crypts of the small intestine and colorectum; and contain secretory .
