Microscopic evaluation

Generally screen for:

  • Gastric adenomas and adenocarcinomas. Further information: Stomach tumor

  • Reactive gastropathy, which is a triad of:[3] - Foveolar hyperplasia (black arrow), generally seen as a tortuosity in the "neck" region of the gastric glands. - Scant acute and chronic inflammatory cells (white arrow). - Smooth muscle hyperplasia (black oval)
