Abstract

Sarcomatoid differentiation can occur within any subdivision of renal cell carcinoma. Although the prevalence of sarcomatoid renal cell cancer has been reported to be anywhere from 1-15% of renal cancers, sarcomatoid non-clear cell renal carcinoma is actually very rare. Studies on these cancers are generally limited to tens of patients. One reason for the paucity of patients with non-clear cell sarcomatoid renal cell cancer is the aggressive nature of this disease. We present a case of sarcomatoid non-clear cell renal carcinoma and review of the treatment for these difficult cases based on the available literature.
