Interestingly, in 8 cases the histological and immunphenotypic data were entirely consistent with the histopathological diagnosis of CCPRCC, but the presence of VHL abnormalities led us to place these samples into the group of low-grade CCRCC with CK7 immunoreactivity and no 3p loss. Here, KRT7 is linked to nonpapillary renal cell carcinoma.
