Hybrid tumour ‘oncocytoma‐chromophobe renal cell carcinoma’ of the kidney: a report of seven sporadic cases

Abstract

In a large series of patients with sporadic RO and CRCC, 10% of the tumours had hybrid morphological features, as described in oncocytosis and Birt-Hogg-Dube syndrome. We were unable to identify any specific clinical characteristic. Most importantly, none of these HT showed any of the radiological characteristics of RO.
