We present the case of a man in his sixties experienced pain in his oral cavity and pharynx. The following day, he experienced epigastric discomfort, increased belching, and flatulence, leading to a visit to our hospital. Esophagogastroduodenoscopy revealed diffuse white granular elevations in the gastric body and fundus. On a magnified endoscopic view, the white granular elevations displayed a central depression in their apex. We initiated symptomatic therapy with mosapride citrate. Histopathological analysis of biopsy specimens from the white granular elevations revealed infiltration of more than 100 eosinophils per high-power field, leading to a diagnosis of eosinophilic gastritis. A follow-up endoscopy conducted 3 months later confirmed the complete resolution of the white granular elevations in the gastric body and fundus. The patient remains under regular follow-up.
