Metanephric adenoma is an extremely rare renal neoplasm, especially in pediatrics. Chemotherapy combined with surgery in metanephric adenoma has not been reported.
We describe a case of metanephric adenoma in a child less than 2 years old, which were treated by chemotherapy combined with surgery.
Nephron sparing surgery was performed after regular chemotherapy, and the pathological result was metanephric adenoma.
Pediatric metanephric adenoma is extremely rare; the clinical manifestations and imaging examinations lack specificity. Nephron sparing surgery is recommended as the preferred treatment for metanephric adenoma. Long-term follow-up and more in-depth molecular genetic research are still needed to determine the benign or malignant of metanephric adenoma and whether chemotherapy drugs have an effect on it.
