Benign mixed epithelial and stromal tumor of the kidney

Abstract

We unified a group of hitherto separately published types of tumors i.e. adult type of cystic nephroma, adult type of mesoblastic nephroma, cystic hamartoma of the pelvis and solid and cystic biphasic tumor of the kidney into a single group of tumors, for which we introduced name 'Benign mixed epithelial and stromal tumor of the kidney'.
