Abstract

Inflammatory fibroid polyp is a relatively rare, benign lesion of gastrointestinal wall which is composed of fibrous connective tissue, blood vessels, and infiltration of eosinophils, These occur mainly in two sites, the distal stomach and the distal ileum. The gastric lesions are almost always situated in the antral region, frequently adjacent to the pyloric sphincter. they have been found in patients from the third through the ninth decades with a medial age in the midsixth decade. There seems to be a sligbt male predominance. The majority of inflammatory fibroid polyps had been reported with pathologic specimen in stomach. These reveal polypoid masses originated mainly in the submucosa of the stomach, As to the diagnosis of submucosal tumor of the stomach, a newly developed diagnostic modality of endoscopic ultrasonography allows us to visualize the structures underlying the gasointestinal wall in a noninvasive manner, and has the great advantage over the conventional modalities such as endoscopy and X-ray examination. We report 4 cases of inflammatory fibroid polyp in ithe stomach, which was diagnosed by the gastrofiberscopy and endoscopic ultrasonography, and treated by surgical operation in 1 case and endoscopic resections in 3 cases, These lesions were demonstrated as hypoechic tumors mainly in the third layer of the gastrie wall with irregular margin and unclear bouadary by endoscopic ultrasonqgraphy. The findings of endoscopic ultrasonography are discussed with the review of the literature.
