Radiologic-pathologic correlation from the Armed Forces Institute of Pathology. Inflammatory fibroid polyp.
The inflammatory fibroid polyp of the stomach, sometimes called eosinophilic granuloma, is a relatively uncommon lesion usually presenting a solitary, benign-appearing filling defect. The differential diagnoses include polypoid adenocarcinoma, hyperplastic mucosal polyp, adenoma, leiomyoma, epitheliod leiomyoma and leiomyosarcoma, and aberrant pancreas. Although difficult to distinguish by gross morphologic features, the inflammatory fibroid polyp shows a distinctive inflammatory response of the mucosal stroma in which eosinophils may be prominent. It is unrelated to the eosinophilic granuloma of lung or bone.
