Presentación de gastroenteritis eosinofílica como brote de colitis con abdomen agudo

Eosinophilic gastroenteritis is rare. Fewer than 30 cases have been published in the Spanish literature, although Kaijser first described this entity in 1937. Its etiology is still unknown and it has frequently been reported to involve the stomach and small bowel, with characteristic eosinophilic infiltration of the bowel wall. The colon has rarely been reported as a site of this condition, which manifests as acute abdominal pain due to intestinal obstruction. We report the case of a 38-year-old woman who presented eosinophilic gastroenteritis. Onset was acute colitis causing acute abdomen. The patient received conservative treatment and responded well to steroids. To our knowledge, such a case has not previously been reported.
