A 54-year-old man with a fibrous polyp of the gallbladder is reported. The patient had no symptoms, but ultrasonography showed an isoechoic polypoid lesion of the gallbladder and subsequent endoscopic retrograde cholangiography demonstrated a irregularly spherical filling defect in the fundus. Under suspicion of a carcinoma in the gallbladder, a cholecystectomy with resection of the liver bed was performed. The mucosa of the gallbladder was almost normal. A pedunculated polyp, 20×17×15 mm in size, was found in the fundus. Histologically, the polyp was composed of loose connective tissue with a vascular network and an inflammatory infiltrate. There was no evidence of malignant change. These findings were consistent with those of fibrous polyp. This type of polyp is very rare.
