Abstract

A 27-year-old Caucasian female was hospitalized three times over a four-month period for recurrent, intermittent abdominal pain associated with nausea and diarrhea. No signs or symptoms of gastrointestinal (GI) bleeding were present. A stool occult blood test and stool enteric pathogen tests were negative. A complete blood count (CBC) revealed a peripheral blood eosinophil count of 1080 cells /µL without any inflammatory reaction. An upper endoscopy showed grossly normal-appearing esophageal and duodenal mucosa; however, a gastric mucosal biopsy showed an eosinophil infiltration of ≥20 eosinophils/high power field (HPF). Based on these findings, she was diagnosed with eosinophilic gastroenteritis (EGE). A definitive diagnosis of EGE should be confirmed with both an analysis of gastrointestinal mucosal biopsy and an elevated peripheral blood eosinophil count. Specifically, histological evaluation of the mucosal tissue must show an eosinophilic infiltration rate of 20 eosinophils/HPF. The diagnosis should be followed by an extensive review of the patient’s allergic disease history.
