Abstract

The mixed epithelial and stromal tumor family of kidney contain neoplasms with biphasic epithelial and stromal component. According to the 2016 World Health Organization Classification, they encompasses a spectrum of tumors ranging from predominantly cystic tumors (adult cystic nephroma) to tumors that are variably solid (Mixed epithelial and stromal tumor-MESTs). We present the case of a 20-year-old woman with an adult cystic nephroma which was verified by immunohistochemical examination.

Keywords: adult; cystic nephroma; kidney; mixed epithelial and stromal tumor.
