TL;DR: The basis for a new grading system was proposed in 2013 by one of the authors and accepted by the World Health Organization for the 2016 edition of Pathology and Genetics: Tumours of the Urinary System and Male Genital Organs.

TL;DR: The classification working group of the International Society of Urological Pathology consensus conference on renal neoplasia was in charge of making recommendations regarding additions and changes to the current World Health Organization Classification of Renal Tumors, with consensus that 5 entities should be recognized as new distinct epithelial tumors within the classification system.

TL;DR: The 2009 International Society of Urological Pathology Consensus Conference in Boston, made recommendations regarding the standardization of pathology reporting of radical prostatectomy specimens, with no consensus as to how the surgical margin should be regarded when tumor is present at the inked edge of the tissue.

TL;DR: Clear cell RCC is the most common subtype and has a less favorable prognosis than do papillary RCC and chromophobe RCC, but collecting duct carcinoma and renal medullary carcinoma are associated with aggressive clinical behavior and a poor prognosis.

TL;DR: This Special Article summarizes the overall recommendations made by the four working groups and is anticipated that this ISUP effort will be valuable to the entire practicing community in the appropriate use of IHC in diagnostic urologic pathology.
