| Solid mixed epithelial and stromal tumors also need to be distinguished from mesoblastic nephroma and metanephric adenofibroma. |
| This mass of mesoblastic cells may be called the metanephric blastema. |
| In kidney development, the metanephric cap mesenchyme contains a population of progenitor cells that give rise to nearly all of the epithelial cells of the kidney. |
| Benign renal tumors are classified into renal cell tumors, metanephric tumors, mesenchymal tumors, and mixed epithelial and mesenchymal tumors. |
| Metanephric Adenoma, Wilms Tumor, and Mucinous Tubular and Spindle Cell Carcinoma. |
