Diagnosis: Sarcomatoid chromophobe renal cell carcinoma with extensive chondrosarcomatous-like differentiation and focal rhabdoid differentiation.

Comment: Sarcomatoid transformation may occur up to 9% of chromophobe renal cell carcinoma and may be unusually prevalent in some countries like Saudi Arabia. The diffuse chondrosarcomatous-like differentiation and the focal rhabdoid feature in this particular case are very rare events.
