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.
- Do not respond to proton pump inhibitors.
Biopsies:
- Should be taken from: upper, mid, lower and submitted in separate containers (eosinophilia present through-out-- to differentiate from GERD).
Associations:
- Atopy.[4]
- Celiac disease.[5]
- Oral antigens, i.e. particular foods.[3]
- Familial association.[3]
- Young ~ 35 years old.[6]
- Male > female (3:1).[6]

Microscopic
Features:[4]
- Mucosa with "abundant eosinophils".
- 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.[9]
Notes "abundant eosinophils":
- Criteria for number of eosinophils/area is highly variable; there is a 23X fold variation in published values and only 11% of studies actually define an area (most studies, only give the number of eosinophils per "HPF")![10]
- Interrater variability is low, i.e. good, if the procedure is standardized.[11]
- The most commonly reported cut points are 15, 20 and 24 eosinophils/HPF, without defining HPF.[10]
- The Foundation Series book[4] says: "> 20/HPF"; this is problematic as "HPF" is not defined (see HPFitis).
- There is a consensus paper[12] that makes note of HPFitis... and then goes on to ignore to whole issue by defining EE as 15/HPF!
- Many microscopes have 22 mm eye pieces and have for their highest magnification objective a 40X. De facto, these people are using the Liacouras et al. definition.[13]
- Eosinophils may be patchy.[14]
DDx:[15]
- Gastroesophageal reflux disease - no mid and proximal involvement.
- Infectious esophagitis.
- Eosinophilic gastroenteritis.
- Hypereosinophilic syndrome.

Sign out
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). Literature valves show a large variation when defining eosinophilic esophagitis and frequently use "HPF" as a measure of area, which is not a standardized measure. [Am. J. Gastroenterol. 102 (10): 2300–13.] Common cut-points are 15 eosinophils/HPF and 20 eosinophils/HPF, where HPF is often undefined. 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. Literature valves show a large variation when defining eosinophilic esophagitis and frequently use "HPF" as a measure of area, which is not a standardized measure. [Am. J. Gastroenterol. 102 (10): 2300 13.] Common cut-points are 15 eosinophils/HPF and 20 eosinophils/HPF, where HPF is often undefined.
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.
