A case of gallbladder metastasis from renal cell carcinoma

Abstract

We report a case of gallbladder metastasis from renal cell carcinoma. A 76-year-old man had undergone right nephrectomy for right renal cell carcinoma 6 years previously. Subsequently, he had undergone resection for skin metastasis from the same renal cell carcinoma. Follow-up ultrasonography showed a gallbladder tumor that had grown to about twice its original size in 1 year 6 months. We performed open cholescystectomy, considering a diagnosis of primary gallbladder cancer. A histopathological examination disclosed clear cell carcinoma as well as renal cell carcinoma and skin metastasis. The patient was diagnosed with gallbladder metastasis of renal cell carcinoma.
