title: Large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma.
abstract: Gallbladder tumors larger than 10 mm in diameter have a high incidence of malignancy. We report an extremely rare case of a large cholesterol polyp of the gallbladder mimicking gallbladder carcinoma. Ultrasonography and computed tomography showed a larger papillary mass in the fundus of the gallbladder with a maximum diameter of about 30 mm, the largest gallbladder polyp ever reported to our knowledge.
