Cystic renal neoplasms. New entities and molecular findings

摘要: Renal neoplasms with dominant cysts represent a broad spectrum of known as well novel renal tumor entities. Established tumors include cystic nephroma, mixed epithelial and stromal tumor, synovial sarcoma multilocular cancer (WHO classification 2004). Novel types have recently been reported, which are also characterized by marked cyst formation. Examples tubulocystic in end-stage disease. These very likely to be included future WHO due their characteristic phenotype molecular features. Cysts clear cell carcinoma frequently coexist the kidneys patients von Hippel-Lindau component many sporadic carcinomas. Multilocular is composed almost exclusively regarded specific subtype cancer. Recent findings suggest that may develop via cyst-dependent mechanism syndrome cyst-independent pathways
