Kidney pathology: Current classification of renal cell carcinoma

Jonathan W. Said, George Thomas, Amnon Zisman

Research output: Contribution to journalArticlepeer-review


This report discusses the new cytogenetic classification of renal cell carcinoma (RCC) and its biological and clinical significance. It describes the four major types (clear cell, chromophil [papillary], chromophobe, and collecting duct) as well as rarer entities, such as small cell carcinoma, cystic RCC, rhabdoid variant of RCC, and unclassified RCC. Sarcomatoid carcinomas are a diverse group representing high-grade transformation of the other types. In addition to a description of the pathologic findings, there is a discussion of tumor markers and prognostic indicators. The clinical significance of the classification is discussed, with reference to recent reports.
