Eosinophilic infiltration of the gastrointestinal tract in children.

Three children had eosinophilic infiltration of the gastrointestinal tract. This entity has two forms--diffuse and circumscribed. The diffuse lesion is confined mainly to the gastric antrum. Surgical resection of this form is seldom necessary. Involvement of the appendix with this form has not been previously described. The polypoid lesion, which may arise in any segment of the gastrointestinal tract, commonly produces secondary gastrointestinal symptoms and is amenable to local surgical excision.
