Renal tumor grading
The purpose of this image base is to provide a comprehensive atlas of renal cell carcinoma. It is planned to include all the morphotypes of renal cell neoplasia recognized by the ISUP Vancouver Classification of 2012 and the Fourth Edition of the World Health Organization Classification due for publication in 2016. This part of the renal project aims to standardize grading according to the new WHO/ISUP Grading Classification . We are aware that not all of these tumor types should be graded. If so, please select Would not grade this case.
