ENDOSCOPIC ULTRASONOGRAPHICFINDINGS OFGASTRIC INFLAMMATORY FIIBROID POLYPS

Abstract

An inflammatory fibroid polyp (IFP) is a su.bmucosal granulorna with the infiltrationof eosinophils. The IFP is a rare disease and there are few reports about the findings ofendoscopic ultrasonography (EUS) of IFPs. We found an IFP in 75-year-old female andexamined it by EUS. An ordinary endoscopic study showed the type 2 polyp (classificationof Yamada) at the gastric antrum. It had reddish surface and an erosion on the center.ELTS indicated a hypoechoic mass lesion mainly located in the 2nd and the 3rd layers of thegastric wall. The border of it was unclear. The echo pattern of the lesion was heterogene-ous and some high echoic spots were recognized. in it. The polyp was removed byendoscopic mucosal resection. The histological examination of it revealed that it iscompatible to the IFP. In this case report, ire compared the EUS findings of the IFP in thiscase to those in other ll cases reported in the previous papers. The characteristic findingsof EUS in IFPs are followings; 1)The lesions are located in the 2nd and/or 3rd layers ofthe gastric wall. 2)The border of the lesions rs not clear. 3)The echo pattern of the lesionsis homogeneous. 4)The echo Ievel of the lesions is law.
