Three Cases of Gastric Inflammatory Fibroid Polyp (IFP) with Special Reference to the Findings of Endoscopic Ultrasonography

We reported the findings of endoscopic ultrasonography (EUS) for three cases with gastric inflammatory fibroid polyp (IFP). Case 1; 63-year old female had a complaint of upper abdominal pain. Upper gastrointestinal endoscopy revealed a protruding lesion 10mm in diameter in the antrum of the stomach. EUS showed an almost uniform hypoechoic mass in the third layer and thickening of the second layer with intact fourth layer of the gastric wall. Case 2; 79-year old female had also a complaint of upper abdominal pain. Endoscopic examination showed a smooth elevated lesion 7mm in diameter in the antrum of the stomach. EUS revealed a hypoechoic mass in the third layer. Case 3; 45-year old male suffered from liver cirrhosis and esophageal varices. Endoscopic examination showed a slightly reddish elevated lesion 10mm in diameter in the corpus of the stomach. EUS also revealed an almost homogeneous hypoechoic mass in the third layer. In three cases, these lesions were demonstrated as hypoechoic tumors in the third layer of the gastric wall by EUS. Endoscopic polypectomy was performed for 3 lesions and were diagnosed as IFP histologically. The lesions were confirmed histologically to exist in the third layer of the gastric wall as expected by the findings of EUS.
