Isolated Eosinophilic Colitis: A Challenging Diagnosis in Search of Criteria

Eosinophils infiltrate the colonic mucosa in response to tissue-invading parasites, as part of eosinophilic gastroenteritis (EoG), or as an isolated presumably allergic phenomenon.

Focal infiltrates around parasite fragments are easily recognized and the simultaneous involvement of stomach or small intestine readily leads to a diagnosis of EoG. In contrast, no established criteria exist for the diagnosis of primary eosinophilic colitis.
