Renal cell carcinoma (RCC) is well known for its propensity to metastasize to various organs，but gallbladder (GB) metastasis from RCC is extremely rare.
A 58-year-old woman underwent radical left nephrectomy for RCC. Three years later, she developed cholecystitis. Abdominal CT showed hyperdense enhanced 24mm tumor at the fundus of the GB. GB carcinoma accompanied by acute cholecystitis was suspected by enhanced CT. We perfomed cholecystectomy and intraoperative pathological examination showed GB cancer within mucosal layer. By final histopathological examination, the tumor indicated clear cell carcinoma and was diagnosed as metastasis to the GB from RCC.
There are 25 cases of solitary asynchronous metastasis from RCC to the GB. 4 cases of those was diagnosed GB metastasis from RCC accompanied by acute cholecystitis.
