title: Synchronous chromophobe and papillary renal cell carcinoma. First report and review of the pathogenesis theories.
abstract: The coexistence of different subtypes of renal cell carcinoma (RCC) within a single kidney is an extremely unusual entity. Presented herein is the case of a 57-year-old man with two RCC of chromophobe and papillary histology. Very few reports in the literature describe double or triple synchronous renal neoplasms. To our knowledge this is the first report of this RCC subtype combination, which might trigger further investigation on the RCC pathogenesis theories.
