We report a case of clear-cell adenocarcinoma of the gallbladder. A 78-year-old woman admitted for evaluation of a gallbladder tumor about 5 cm in diameter found in ultrasonography. Enhanced computed tomography (CT), and magnetic resornance imaging (MRI) showed a hypervascular gallbladder tumor. Cholecystectomy with liver resection of segments 4a and 5 was performed on suspicion of gallbladder carcinoma. Histologically, the neoplasm consisted mainly of a clear-cell component and the presence of dysplasia adjacent to carcinoma. The definitive diagnosis was clear-cell adenocarcinoma of the gallbladder, an exceedingly rare malignant neoplasm.
