title: Four bilateral synchronous benign and malignant kidney tumours: a case report.
abstract: Synchronous occurrence of benign and malignant kidney tumours is very rare. We present the case of a 63-year-old female patient who underwent a bilateral partial nephrectomy after being diagnosed with bilateral kidney tumours by ultrasonography and a computed tomography scan. Histopathological analysis of the left kidney tumour mass revealed a chromophobe renal cell carcinoma. In the right kidney specimen clear cell renal cell carcinoma was found along with a small angiomyolipoma and renomedullary interstitial cell tumour. There were no indications for subsequent chemotherapy. At present, three years after the surgery, the patient has had no signs of relapse and maintains normal renal function.
