A 52-year-old woman with a fibrous polyp of the gallbladder is reported. The patient had an upper abdominal pain, so she underwent gastrofiberscopy and ultrasonography. The latter showed a polypoid lesion which had both hyperechoic and solid echo elements. Subsequently drip-infusion cholangiography revealed a nodular spherical filling defect in the fundus. Under suspicion of carcinoma of the gallbladbladder, a cholecystectomy with dissection of the lymnph node around the common bile duct was performed. We found a pedunculated polyp, 17×25×17 mm in size, on the fundus and normal mucosa. The polyp was composed of loose connective tissue with inflammatory infiltration and a vascular network. There was no evidence of a malignancy. These findings were consistent with those of a fibrous polyp. These polyps tend to enlarge more than 10 mm in size. In ultrasonography they are shown small nodular or granular surface and solid element. Our case is the second largest one of the 22 fibrous polyps ever reported.
