Caveolin-1 immunohistochemical analysis in differentiating chromophobe renal cell carcinoma from renal oncocytoma.


Chromophobe renal cell carcinoma (ChRCC) and oncocytoma might mimic each other histologically. We studied the immunohistochemical staining pattern of caveolin-1 in 21 ChRCCs and 26 oncocytomas and compared it with cytokeratin (CK) 7 to evaluate its usefulness in differentiating these 2 neoplasms. All 21 ChRCCs (100%) were positive for caveolin-1, 20 of… (More)
