A case of bilateral renal cell carcinoma in polycystic kidneys.

The authors present the seventh reported case of bilateral renal cell carcinoma in polycystic kidneys. They review the literature on benign and malignant tumours in polycystic kidneys emphasizing the diagnostic problems created by this condition. The diagnosis can be made by renal angiography. Therefore the authors suggest that this procedure should be carried out in all patients with polycystic renal disease who have hematuria.
