[Adenocarcinoma of the kidney associated with polycystic kidney treated by conservative surgery (apropos of a case)].

The authors report a case of renal cell carcinoma discovered incidentally in a 52-year-old woman with hepatorenal and pancreatic polycystic disease. Treatment consisted of partial nephrectomy with no adjuvant therapy. After a 3-year follow-up, the patient is still alive with normal renal function and no signs of recurrence. The pathogenesis and therapeutic modalities are discussed in the light of a review of the literature.
