Hybrid renal cell carcinoma (HRCN) is a rare type of renal tumor with characteristic pathologic features, including oncocytic and chromophobe cellular content.
Hybrid renal cell carcinoma (HRCN) shows more favorable prognosis than renal cell carcinoma. The early-stage tumors show favorable outcome, and postoperative regular clinical and radiological follow-up is adequate in most cases.
HT are characterized by the association of both oncocytes and chromophobe cells (CRCC) within the same tumour.
They have been described in patients with oncocytosis and Birt-Hogg-Dube syndrome.
In a 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 (#19154497#).
