چکیده
Metanephric adenoma (MA) is a rare epithelial neoplasm of the kidney. Most of them are benign tumors. We herein report two cases of metanephric adenoma including different histological subtypes, such as classic MA, malignant MA. The first case is a 4-year-old child with a soft tissue density mass in right kidney which has been proved benign MA. The second case is a 56-year-old man with a mass in left kidney which is malignant MA. We distinguish MA from other lesions in the aspects of computed tomography imaging and immunohistochemistry.
