Eosinophilic Gastroenteritis: Still a Diagnostic Challenge

Abstract

<b><i>Introduction:</i></b> Eosinophilic gastroenteritis (EoG) is a rare condition with a yet poorly understood pathophysiology. <b><i>Case Presentation:</i></b> We report on a case of a 36-year-old woman with a history of atopy presenting with nausea, abdominal discomfort, weight loss, and ascites. Laboratorial analysis revealed peripheral eosinophilia and a slight elevation of inflammatory markers. The patient pursued medical assistance several times with a delay in the diagnosis. The pathway to the diagnosis of EoG with serosal infiltration and further management is presented. <b><i>Discussion:</i></b> Despite being diagnosed by exclusion, it is important to suspect EoG with subserosa involvement in patients presenting with the uncommon association of peripheral eosinophilia and ascites, particularly if there is a history of atopy.
