A Case of Postpartum Eosinophilic Gastroenteritis and Review of the Literature

Eosinophilic gastroenteritis (EG) is a rare disease of unknown etiology that can involve any area of the gastrointestinal (GI) tract. It can be classified into three major types: predominantly mucosal, muscularis, or subserosal form. Diagnosis of EG is confirmed after the exclusion of other disorders having similar features, such as parasitic infection, carcinoma, allergy, and autoimmune conditions such as Churg-Strauss disease. Correct diagnosis hinges on the presence of eosinophilic infiltration of one or more areas of the GI tract, without extraintestinal involvement. We present the case of a 30-year-old female with symptoms of EG 26 days after delivery. After corticosteroid and montelukast treatment for 2 weeks, all symptoms and objective clinical findings disappeared. Although numerous cases of this disorder have been described, to our knowledge this is the first case of postpartum EG. This case highlights the need to include this entity in the differential diagnosis of postpartum GI disorders
