A Case of Inframmatory fibroid polyp in the fornix

Abstract

A 76-year-old woman was admitted to our hospital for an irregular elevated lesion of 20 mm in diameter located in the fornix of the stomach. Endoscopically carcinoma was highly suspected, but biopsy specimen showed granuloma with invasion of chronic inflammatory cells. EUS suggested a possibility of submucosal tumor. The shape of this lesion changed quickly to the flat after repeated biopsy. Endoscopic resection was performed to obtain the diagnosis. Histopathologically, inflammatory cell infitration was prominent, diagnosing eosinophilic granuloma (inframmatory fibroid polyp ; IFP) of the stomach. IFP in the fornix in the stomach is rare. In addition, this patient received gastroscopy one year before this episode, showing no evidence of tumor at all.
Endoscopic resection is useful for diagnosis of IFP, because it is difficult to diagnose IFP from biopsy specimens.
