Cystic Partially Differentiated Nephroblastoma
General Information About Cystic Partially Differentiated Nephroblastoma
Cystic partially differentiated nephroblastoma is a rare cystic variant of Wilms tumor (1%), with unique pathologic and clinical characteristics. It is composed entirely of cysts, and their thin septa are the only solid portion of the tumor. The septa contain blastemal cells in any amount with or without embryonal stromal or epithelial cell type. Several pathologic features distinguish this neoplasm from standard Wilms tumor.
