Eosinophilic esophagitis, abbreviated EE, is relatively uncommon pathology of the esophagus with some similarities to gastroesophageal reflux disease (GERD).
General
- The current thinking is that it is a clinico-pathologic diagnosis.[1]
Clinical:
- Dysphagia[2] - classic presentation.
- Dyspepsia.
- Often mimics gastroesophageal reflux disease (GERD).[3]
Treatment:
- Avoid exacerbating antigens.
- Topical corticosteroids, e.g. fluticasone.
Note on treatment:
- The classic teaching was that EE does not respond to proton pump inhibitors; thinking on this has evolved.[4]
Biopsies:
- Should be taken from: upper, mid, lower and submitted in separate containers (eosinophilia present through-out-- to differentiate from GERD).
Associations:
- Atopy.[5]
- Celiac disease.[6]
- Oral antigens, i.e. particular foods.[3]
- Familial association.[3]
- Young ~ 35 years old.[7]
- Male > female (3:1).[7]

Microscopic
Features:[5]
- Mucosa with abundant eosinophils - the consensus on eosinophils per area is 60/mm*mm.[4]
- Basal cell hyperplasia.
- Three cells thick or >15% of epithelial thickness.
- Papillae elongated.
- Papillae that reach into the top 1/3 of the epithelial layer - definition for GERD.[10]
Note:
- Many microscopes have an eye piece diameter of 22 mm. Thus, the field area (for a "HPF") with the 40x objective is ~0.2376 mm*mm. This works out to approximately 15 eosinophils/HPF.
DDx:[11]
- Gastroesophageal reflux disease - no mid and proximal involvement.
- Infectious esophagitis.
- Eosinophilic gastroenteritis.
- Hypereosinophilic syndrome.

Sign out
A. Distal Esophagus, Biopsy:
- Squamous mucosa with basal cell hyperplasia, abundant intraepithelial
eosinophils, edema, and papillary elongation, see comment.
- NEGATIVE for columnar type epithelium.
- NEGATIVE for dysplasia.
B. Mid Esophagus, Biopsy:
- Squamous mucosa with basal cell hyperplasia, abundant intraepithelial
eosinophils, edema, and papillary elongation, see comment.
- NEGATIVE for dysplasia.
COMMENT:
There are approximately 35 eosinophils per 0.2376 mm*mm (1 HPF) in
both Part A and Part B.
The above findings are suggestive of eosinophilic esophagitis in the proper
clinical context.
Block letters
ESOPHAGUS, DISTAL, BIOPSY: - SQUAMOUS MUCOSA WITH BASAL CELL HYPERPLASIA, ABUNDANT INTRAEPITHELIAL EOSINOPHILS, EDEMA, AND PAPILLARY ELONGATION, SEE COMMENT. - STAINS (PAS-D, GMS) NEGATIVE FOR MICROORGANISMS. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR DYSPLASIA. COMMENT: There are approximately 65 eosinophils per 0.2376 mm*mm (1 HPF). The above findings are suggestive of eosinophilic esophagitis in the proper clinical context.
Patchy eosinophils
ESOPHAGUS (DISTAL), BIOPSY: - SQUAMOUS MUCOSA WITH BASAL CELL HYPERPLASIA, INTRAEPITHELIAL EDEMA AND ONLY FOCALLY ABUNDANT INTRAEPITHELIAL EOSINOPHILS, SEE COMMENT. - COLUMNAR EPITHELIUM WITH MODERATE CHRONIC INFLAMMATION, AND PANCREATIC ACINAR METAPLASIA. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR DYSPLASIA AND NEGATIVE FOR MALIGNANCY. COMMENT: One high power field (field diameter 0.55 mm) has 25 eosinophils. The findings are compatible with gastroesophageal reflux; however, eosinophilic esophagitis is also a consideration. Clinical correlation is required.
Histology suggestive
ESOPHAGUS, BIOPSY: - SQUAMOUS MUCOSA WITH MARKED BASAL CELL HYPERPLASIA, FOCALLY ABUNDANT INTRAEPITHELIAL EOSINOPHILS, EDEMA, AND PAPILLARY ELONGATION, SEE COMMENT. - NEGATIVE FOR INTESTINAL METAPLASIA. - NEGATIVE FOR DYSPLASIA. COMMENT: Focally, there are approximately 35 eosinophils per 0.2376 mm*mm (1 HPF). The above findings raise the possibility of eosinophilic esophagitis; clinical correlation is suggested. A re-biopsy including a portion of the proximal esophagus could be considered.
