RESUMEN
We report the case of a 40-year-old male patient admitted to the surgery ward in our hospital for recent abdominal pain, abdominal distention and fever. He had a history of similar abdominal pain and distention; for which he had undergone a laparotomy. Laboratory data revealed leukocytosis with eosinophilia [42%]. Upper gastrointestinal endoscopy showed diffuse severe erythematous pangastritis. Biopsies were taken from the esophagus which showed 10-15 eosinophils in each high power field. The ascitic fluid was straw-colored and sterile with 90% eosinophils. Therefore, the patient was treated with prednisolone [30 mg/day] and was diagnosed with an eosinophilic gastroenteritis syndrome with subserosal presentation. The patient recovered and eosinophilia improved within a few days
