Gallbladder metastasis from renal cell carcinoma: A case report and literature review

Renal cell carcinoma has a propensity to metastasize to lung, bone, liver, brain, adrenal glands and the contralateral kidney. The proportion of metastatic RCC at diagnosis is estimated to be about 30–40%, and about 20–50% patients will develop metastasis after radical nephrectomy. Gallbladder metastasis from RCC is rare and is found in only about 0.6% of patients at autopsy.1 We present a case of metachronous metastasis of clear cell carcinoma to the gallbladder in a 55-year-old woman one year after radical nephrectomy.
