Eosinophilic Gastroenteritis: A Rare Case Report

Eosinophilic gastroenteritis (EGE) is a rare disease characterized by eosinophilic infiltration and peripheral eosinophilia. It can be seen anywhere in the gastrointestinal tract. It is diagnosed in the biopsies taken during endoscopic examination to the patients with abdominal pain and chronic diarrhea. A 40-year-old woman was admitted with abdominal pain and chronic diarrhea. She has not any disease, food, pollen, or drug allergy in her medical history. Leukocyte: 19,400/mm3 (neutrophil: 19.9%, eosinophil: 57.4%, lymphocyte: 16.5%), platelet: 281,000/ mm(3), immunoglobulin E: 1721 IU/mL (normal range: 20–100 IU/mL) was counted in her blood examination. The duodenal biopsy was reported as EGE. We applied methylprednisolone 20 mg/day. With this treatment, the patient's symptoms regressed. In this article we present a case of chronic diarrhea diagnosed EGE. The first step in diagnosing is suspecting EGE. It should be borne in mind in patients with chronic diarrhea.
