Microscopic examination
The main finding to look for is intestinalized mucosa (Barret's esophagus), which is defined as the presence of columnar epithelium with goblet cells.[1] A true goblet cell should have rounded shape, clear to bluish cytoplasmic mucin, and be randomly scattered.[2] The mucin usually indents the nucleus.[2]
At least in absence of Barret's esophagus, look for signs of (reflux) esophagitis.
Barret's esophagus
The main diagnostic sign of Barret's esophagus is the presence of goblet cells:

-
In incomplete intestinal metaplasia, there are both foveolar cells and goblet cells, latter indicated by arrows, and having a slightly bluish color compared to the apical cytoplasm of foveolar cells.

Further information: Barret's esophagus
Esophagitis
Look for signs of (reflux) esophagitis, mainly:[4]
- 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.
- Basal cell hyperplasia exceeding 15 - 20% of the epithelial thickness.
- Stromal papillae reaching upper third of the epithelium.
- Ballooned squamous cells
-
An intra-epithelial eosinophil (characterized by its bilobed nucleus despite scant visible eosinophilic cytoplasm)
Report
On this resource, the following formatting is used for comprehensiveness:
- Minimal depth
- (Moderate depth)
- ((Comprehensive))
Examples:
| (GE junction, biopsy:) Squamous mucosa without significant histopathologic changes. (Negative for gastric mucosa or intestinalized (Barrett's) mucosa.) |
| (GE junction, biopsy:) Gastroesophageal junctional mucosa with chronic inflammation and reactive changes(, non-specific. Negative for intestinalized (Barrett's) mucosa.) |
