The 2012 ISUP Vancouver and 2016 WHO classification of adult renal tumors: changes for common renal tumors
Abstrakt
In the past decade, the histological classification of renal neoplasia has undergone significant changes. Many new entities with distinct clinical, pathological and genetic features have been identified.
In addition, common and established tumor entities have been further refined with regard to their pathological and genetic features. These changes have been incorporated in the 2012 International Society of Urological Pathology Vancouver classification and also in the 2016 World Health Organization classification.
This article will focus on the new discoveries of clinical, pathological and molecular characteristics of the common renal tumors, including clear cell renal cell carcinoma, multilocular cystic renal neoplasm of low malignant potential, papillary renal cell carcinoma, chromophobe renal cell carcinoma, mucinous tubular and spindle cell renal cell carcinoma, collecting duct carcinoma, renal medullary carcinoma, papillary adenoma, oncocytoma, metanephric tumors, angiomyolipoma, and mixed epithelial and stromal tumor.
