All are features of Hypernephroma except

RCC commonly occurs in upper pole of kidney . The classic triad of loin pain, loin mass and haematuria is seen in <10% of patients with a renal tumour. Nowadays, the majority of diagnoses result from incidental findings. This shift is a consequence of the widespread use of USS and CT imaging, performed for other reasons.
