[Acute abdomen caused by eosinophilic enteritis: six observations].

Background: Eosinophilic enteritis is a rather rare condition characterized by infiltration of the gastrointestinal tract by eosinophils; as a casue of acute abdomen it is really exceptional. The etiology is unclear and its description in the literature is sparse, but associations have been made with collagen vascular disease, inflammatory bowel disease, food allergy and parasitic infections as it was confirmed in one of our pathologic studies.

Clinical Cases: From 1997 to 2011 six cases of eosinophilic enteritis that involved a small bowel segment were diagnosed.
