Metastasis of the gallbladder in clear cell renal carcinoma.

Metastasis of the gallbladder due to renal cell tumors is rare. We present a case of gallbladder and metachronous left adrenal metastasis at six months follow-up, which demonstrates the importance of radiological tests and histology when making a definitive diagnosis. Clinical findings are not specific enough to arrive at a final diagnosis. However, immunohistochemistry is necessary to differentiate between primary and secondary metastatic tumors. Cholecystectomy should be performed to obtain a definitive diagnosis and to improve survival in cases of single lesions in the gallbladder.
