*Changes may be focal.
*[[PPI effect]] may be seen in a concurrent [[stomach|gastric]] biopsy.
 
DDx:
*[[Eosinophilic esophagitis]] - characterized by similar histomorphologic features. The key difference is: more [[eosinophil]]s.
*[[Barrett's esophagus]] - intestinal metaplasia may be minimal.

ESOPHAGUS (DISTAL), BIOPSY:
- COLUMNAR EPITHELIUM WITH INTESTINAL METAPLASIA AND MODERATE CHRONIC INFLAMMATION,
  SEE COMMENT.
- SQUAMOUS MUCOSA WITH BASAL CELL HYPERPLASIA, INTRAEPITHELIAL EDEMA AND RARE

COMMENT:
The findings are consistent with Barrett's esophagus in the appropriate endoscopic setting.
