[Idiopathic hypereosinophilic syndrome with predominant digestive manifestations or eosinophilic gastroenteritis? Apropos of 2 cases].

We report two cases of hypereosinophilic syndrome with predominant gastrointestinal signs, which could have been mistaken for eosinophilic gastroenteritis. In the first case, the patient presented with eosinophilic ascites; documentation of pulmonary involvement allowed to easily establish the diagnosis. In the second case, the patient presented with diarrhea and malabsorption; gastrointestinal and pancreatic involvement seemed isolated.
