Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Microscopic evaluation
Generally screen for:
Gastric adenomas and adenocarcinomas.
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)

Microscopy report
Example in case of normal findings:
| (Gastric, biopsy:) Gastric mucosa without significant histopathologic changes. ((Negative for Helicobacter pylori organisms on H&E slide.)) |
Notes
