title: [Three cases of renal cell carcinoma with sarcomatoid differentiation].
abstract: Renal cell carcinoma with sarcomatoid differentiation has an incidence of 4-6%. It occurs more frequently with clinical advanced presentation in relation to the greater biological aggressiveness. This variant was also found both in transplanted kidneys and in patients with von Hippel-Lindau syndrome. The authors present three cases of cancer all clinically evolving to rapidly progressive conditions. The pathologic staging was, respectively: Case 1 pT4 N0 M0 G4 case, Case 2 P G4 T3a N2 M0, Case 3 pT3a N0 M1 G4. The clinical responses related to protocols with VEGF drugs that seem to have better clinical response compared to immunotherapy are still being studied. From the pathologic point of view it is necessary, for all renal cell cancers, to search and identify the sarcomatoid components that, although poorly represented, give a negative prognosis.
