Eosinophilic Enterocolitis: An Exceedingly Rare Entity.

Eosinophilic enterocolitis is an exceptionally rare condition with few described cases in the literature, representing the least frequent manifestation of the wide spectrum of eosinophilic gastrointestinal disorders. We describe a case of a young male patient presenting with a panmural form of the disease, manifested by abdominal pain, distention, and watery diarrhea with 4 days of evolution, bowel wall thickening, and ascites. Eosinophilic ascites is probably the most unusual presentation form of this entity. It poses a diagnostic challenge because of its nonspecific symptoms, associated with the absence of standardized histological criteria, hence requiring a high level of suspicion. There is also no consensus regarding treatment: it should be individualized according to the patient's age and severity of symptoms.
