Comprehensiveness
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Microscopic evaluation
Look at least for esophagitis:
Esophagitis
Look for signs of (reflux) esophagitis, mainly:[1]
- Inflammatory cells, especially when intra-epithelial. Neutrophils confer a diagnosis of acute inflammation, while plasma cells, eosinophils and excess T cells confer a diagnosis of chronic inflammation. In eosinophil-predominant inflammation, also evaluate as suspected eosinophilic esophagitis.
- Basal cell hyperplasia exceeding 15 - 20% of the epithelial thickness.
- Stromal papillae reaching upper third of the epithelium.
- Loss of orientation of superficial epithelial cells.
- Ballooned squamous cells
An intra-epithelial eosinophil (characterized by its bilobed nucleus despite scant visible eosinophilic cytoplasm)
Microscopy report
Example normal report for an esophagus biopsy:
| (Middle third esophagus, biopsy:) Squamous mucosa without significant histopathologic changes. ((Negative for eosinophilic esophagitis.)) |
Example report with signs of reflux:
| (Mid esophagus, biopsy:) Squamous mucosa with reactive changes consistent with reflux. ((Negative for eosinophilic esophagitis.)) |
