Chromophobe renal cell carcinoma with rare distant metastasis

ABSTRACT

Metastasis accounts for the most common tumor of the central nervous system (CNS) in adults. Renal cell carcinoma (RCC) is one of the common carcinoma showing brain metastasis, with a predilection for clear cell variant. Chromophobe RCC (ChRCC) in contrast to clear cell RCC shows far less common distant metastasis. When they metastasize, commonly involve the liver, lungs, and lymph nodes. ChRCC metastasizing to the brain is extremely rare. Isolated brain metastasis from RCCs is also uncommon. We report an unusual case of a 54-year-old woman with ChRCC with isolated metastasis to the brain, 2 years after radical nephrectomy for renal mass.
