Gallbladder's clear cell renal cell carcinoma metastasis: A systematic review of the literature

Renal cell carcinoma (RCC) represents 2% of all cancers, being the clear cell subtype the most common among renal tumors (70-80%). RCC is well know for its capacity to metastasize in an early stage of the disease, gallbladder metastases are consider extremly rare. The symptomatology goes from asymptomatic to cholecystitis like-symptoms. Ultrasonography, may be often, the first diagnostic tool, tumors can appear under different hyperechoic masses without acoustic shadowing. Metastasectomy has gained a wide consensus because of the possibility of extending survival, keeping in mind the importance of selection of the ideal candidate for it. The surgical procedure will be chosen upon the extent of the disease, it may go from a simple cholecystectomy to a cholecystectomy associated with a wedge/right hepatic lobectomy for curative purposes.
