# Eosinophilic enterocolitis in duodenum, ileum, and colon: A case report

## TL;DR

This case report describes a rare instance of eosinophilic gastroenteritis affecting multiple parts of the gastrointestinal tract and successful treatment with corticoids.

## Contribution

The novelty lies in reporting an infrequent presentation of EGE in both small and large intestines as an undifferentiated gastrointestinal disease.

## Key findings

- Eosinophilic infiltration was observed in the duodenum, ileum, and colon.
- The patient showed improvement with corticoid treatment.
- This case contributes to understanding the clinical management of rare EGE presentations.

## Abstract

Eosinophilic gastroenteritis (EGE) is a rare disease which mainly consists of an abnormal eosinophile infiltration of the gastrointestinal tract. It’s classified according to its location: eosinophilic esophagitis, eosinophilic gastritis, eosinophilic enteritis (including duodenum, jejunum and/or ileum) and eosinophilic colitis and degree of infiltration (mucosal, muscular, serosal). Depending on eosinophile concentration, type of EGE and the patient’s condition it may manifest with different clinical presentations such as functional dyspepsia, abdominal pain, irritability, hypoproteinemia, diarrhea, anemia, among others. Few research has been done on such an uncommon pathology to the extent that treatment evidence is mostly limited to small case series. This case study reports an infrequent presentation of EGE in the small and large intestine as an undifferentiated gastrointestinal disease and successful corticoid management given to the patient in order to further broaden knowledge on this subject and facilitate an established clinical conduct for the treating physician.
