Renal Mixed Epithelial and Stromal Tumor
Renal mixed epithelial and stromal tumor is an uncommon complex biphasic neoplasm which occurs in adults.
The tumor comprises less than 1% of all renal neoplasms.
The mean age is around 50 years.
There is a striking female predominance. The tumors are related to hormonal factors (Adsay et al. 2000).
There is no site predominance.
It is typically cured by nephrectomy.
Renal mixed epithelial and stromal tumor is an indolent tumor, although malignant transformation has been reported with a morphology resembling stromal sarcoma and carcinosarcoma (Svec et al. 2001).
The tumor is a solid or solid and cystic mass.
