A Case of Inflammatory Fibroid Polyp in the Duodenum / 대한소화기내시경학회지

ABSTRACT

Inflammatory fibroid polyp is a relatively uncommon, localized benign lesion of the gastrointestinal wall. It is seen mostly as a single entity and the majority of inflammatory fibroid polyps have been reported with pathologic examination in the stomach but rarely in small intestines. A 70-year-old woman was presented with intermittent epigatric discomfort and gastroduodenoscopy showed a polypoid lesion with oval shaped, central depression, and normal mucosal covering. Endoscopic ultrasonography showed 8x6 mm sized hypoechoic tumor which was located mainly in the third layer of the duodenal wall with indistinct margin. The tumor was successfully removed by endoscopic resection after the injection of hypertonic saline solution with epinephrine and banding. The tumor consisted of loose fibrous stroma, small blood vessels and inflammatory cells. We present a case of inflammatory fibroid polyp of the duodenum with review of the literatures.
