Asymptomatic Eosinophilic Infiltration with Endoscopic and Histological Findings Consistent with Eosinophilic Gastritis

Eosinophilic gastritis often presents with gastrointestinal symptoms in the absence of abnormal endoscopic findings. On the other hand, endoscopic changes due to eosinophilic infiltration in an asymptomatic patient are rare. A 29-year-old woman with a history of asthma on steroid inhalers presented for an annual medical checkup. Esophagogastroduodenoscopy revealed diffuse white granular patches in the body of the stomach, suggestive of eosinophilic gastritis. Histology showed over 100 eosinophils per high-power field, also consistent with eosinophilic gastritis. As the absence of symptoms precluded the diagnosis of eosinophilic gastritis, the patient was diagnosed with asymptomatic eosinophilic infiltration of the stomach.
