[Multilocular cystic renal cell carcinoma: report of a case].

: We report a 76-year-old man with a multilocular cystic renal cell carcinoma resembling a multilocular renal cyst by radiological diagnosis. His creatinine clearance was 43 ml per minute and we carried out simple enucleation, to avoid renal failure after radical nephrectomy and because of low percentage of local recurrence after renal conservative surgery of low stage renal cell carcinoma. We have been following up the patient carefully.
