Eosinophilic Gastroenteritis : Brief Review.

Eosinophilic gastroenteritis (EGE) is a rare disease which belongs to primary eosinophilic gastrointestinal disorders (primary EGIDs), characterized by an accumulation of eosinophils in the gastrointestinal (GI) tract and is strongly associated with atopy and allergy. The clinical presentations vary depending on the site and depth of eosinophilic intestinal infiltration. Radiology pictures may show irregular thickening of the folds, but these findings can also be present in other conditions like inflammatory bowel disease and lymphoma. The endoscopic appearance is also nonspecific. The definite diagnosis requires biopsy for histological evidence of GI eosinophilic infiltration and clinicians make the diagnosis in correlation with and by exclusion of other possible causes of eosinophilic infiltration. Because EGE is a rare disease, the treatment is based on limited case reports and clinicians' experience. Corticosteroids are the mainstay of therapy. The prognosis of EGE is relatively good when patients receive timely and proper treatment. © Acta Gastro-Enterologica Belgica.
