Metastatic renal cell carcinoma in the gallbladder is extremely rare, with reported frequencies of less than 0.6% in large autopsy reviews. Only 40 cases were reported in the literature. We report a first case of gallbladder polypoid tumor revealing metastatic clear cell renal cell carcinoma, which demonstrates the importance of radiological tests, histology and immunohistochemistry when making a definitive diagnosis. These examinations also allow differentiating metastatic clear cell renal cell carcinoma from other polypoid lesions in the gallbladder with clear cell morphology. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in case of solitary metastatic renal cell carcinoma.
