Gallbladder metastasis from renal cell carcinoma (RCC) is rare, and reports on metastasis to gallbladder alone is ever rarer. We herein report a case of gallbladder metastasis from RCC. A 65-year-old male underwent right nephrectomy for RCC six years earlier. At a urology outpatient clinic, ultrasonography (US) demonstrated a gallbladder tumor, and he was referred to our department. US, CT, MRI and EUS revealed a tumor with a diameter 10mm in the neck of the gallbladder.
He underwent open cholecystectomy with resection of gallbladder bed. Permanent pathological diagnosis demonstrated gallbladder metastasis from RCC (clear cell type). Metastasis to gallbladder alone seems extremely rare. Gallbladder metastasis of RCC should be considered in patient with gallbladder tumor with a past medical history of RCC for which good prognosis can be expected by cholecystectomy.
