Chromophobe renal cell carcinoma (ChRCC) is a distinct histologic subtype of RCC and accounts for approximately 5% to 10%. The prognosis for ChRCC is considered to be better than those for other types of RCC. Sarcomatoid transformation occasionally occurs and has been presented as a predicting factor of poor prognosis. However, there has been a scarcity of reports on aggressive type of ChRCC without sarcomatoid change. Here we report an unusual case of aggressive variant of ChRCC with hilar lymph node metastasis, with tumor necrosis and without sarcomatoid change. In addition, this case was accompanied by synchronous occurrence of tonsillar squamous cell carcinoma. (Korean J Urol Oncol 2013;11:94-97)
