Eosinophilic gastroenteritis

Eosinophilic gastroenteritis is a rare clinicopathogenic entity of an unknown aetiology in which a variety of digestive symptoms are associated to the eosinophilic infiltration in the intestinal wall. The clinical features depend on the site of eosinophilic infiltration, and the association with peripheral eosinophilia is very frequent. The radiologic findings were not specific and the diagnostic is based on the endoscopic and/or peroral gastrointestinal biopsy. The response to steroid therapy is spectacular. The etiology is unknown but we review the recent literature.
