[Multilocular cystic renal cell carcinoma]

Multilocular cystic renal cell carcinoma is an uncommon variant recently described of renal cell carcinoma. Analyze clinicopathological features, imaging findings and prognosis and therapeutic options of this tumor. The authors reported two cases of multilocular cystic renal cell carcinoma arising in 68 and 39 year old men. They were admitted with pain in the lumbar region and/or haematuria. The imaging findings were a renal neoplasm with cystic and solid areas. The pathologic findings confirm the diagnosis of multilocular cystic renal cell carcinoma. Multilocular cystic renal cell carcinoma, usually identified at earlier stages, had slower growth rate and was therefore associated with a better prognosis and longer survival than conventionnal renal cell carcinoma
