A Rare Case of Eosinophilic Gastroenteritis in a Neonate with Fever

Abstract

Eosinophilic gastroenteritis is a member of eosinophilic gastrointestinal (GI) diseases and is characterized by the accumulation of eosinophils within the GI tract. Common symptoms of eosinophilic gastroenteritis are vomiting, abdominal pain, dysphagia, and weight loss, but rare fever in neonate. This report describes a 10-day-old boy who developed fever, bloody mucoid stool, and bilious vomiting resulting from eosinophilic gastroenteritis, mimicking sepsis. Sigmoidoscopy and pathologic findings revealed mucosal edema, small hemorrhagic spot, and segmental erythemoid edema in the colon and increased number of eosinophils in the lamina propria with intraepithelial eosinophils. After breast milk feeding with restriction of milk from the mother for 6 months, specific immunoglobulin to milk was class 0 (class 3, previous). The boy restarted formula feeding, and he had no fever and GI symptoms.
