Answer 5 Papillary renal cell carcinoma. There are 5 commonly recognized histologic subtypes of renal cell carcinoma: clear cell, papillary, chromophobe, collecting duct, and oncocytoma. Of these subtypes, papillary renal cell carcinoma is considered most likely to present as multifocal tumors in the same kidney.5 This likelihood mandates complete exposure of the entire renal surface during partial nephrectomy and the use of intraoperative ultrasonography to avoid missing small tumors.
