title: [A case of eosinophilic gastroenteritis with ring-like discoloration in the lower end of the esophagus].
abstract: We report the case of a 15-year-old Japanese boy with eosinophilic gastroenteritis. The patient complained of abdominal pain and watery diarrhea and had a history of allergic rhinitis. Laboratory data on admission showed leukocytosis with remarkable eosinophilia. Microscopic examination of the biopsied specimens taken from the esophagus, stomach, duodenum, lower ileum and colon showed eosinophilic infiltration. Especially in the lower esophagus, there was a ring-like discoloration with remarkable eosinophil infiltration. We diagnosed eosinophilic gastroenteritis and his clinical symptoms and eosinophilia improved following starting corticosteroid therapy. After 5 months therapy with prednisolone, discoloration of upper digestive tract disappeared. There have been no reports describing discoloration in the lower end of the esophagus seen by gastroscopy.
