A rare case of giant chromophobe renal cell carcinoma with sarcomatoid differentiation: Treatment and prognosis.

Chromophobe renal cell carcinoma (RCC) with sarcomatoid differentiation is an infrequent entity. In the current era of advanced imaging techniques, RCCs are usually detected in early stages, and a localized giant tumor is rarely encountered. Recently, we encountered a patient with a localized giant RCC, which was 36 cm in the largest dimension and weighing 5.1 kg, which was resected entirely but presented relapse and succumbed within 3 months of surgery.
