Large mixed epithelial and stromal tumor of the kidney masquerading as metastatic renal cell carcinoma.
We report the case of a 39-year-old woman with a large right renal mass 20 cm in size with heterogeneous solid and cystic components as well as concurrent liver lesions suspicious for metastatic renal cell carcinoma. Surgical extirpation of the renal mass and liver lesions was performed laparoscopically with the pathological analysis revealing a rare renal neoplasm--mixed epithelial and stromal tumor of the kidney--and adenomas of the liver.
