Metastatic renal cell carcinoma of gall bladder

الملخص EN

Renal cell carcinoma (RCC) is well known for its propensity to metastasize to unusual sites.

Metastasis to the gall bladder (GB) has been reported in the literature rarely.

We herein report an interesting case of metastatic RCC, which presented with cholecystitis.

Gall bladder is a rare site of metastasis of RCC.

Polypoid lesions of the GB in patients who have a synchronous or a prior history of RCC should be considered as metastatic lesions.

It needs to be differentiated from primary clear cell carcinoma of the GB with the help of immunohistochemistry.
