- Abstract:
- Objective To explore the clinical characteristics,diagnoses and treatments of metanephric adenoma in children.Methods From June 2008 to December 2021,8 children were diagnosed as metanephric adenoma.Imaging features,surgical approaches,pathological findings and prognoses were reviewed retrospectively.Results There were 7 boys and 1 girl with an average age of 67(16-124)months.The involved side was right(n=7)and left(n=1).The presenting manifestations were abdominal pain(n=2),distention(n=1),polycythemia(n=1)non-specific(n=4).After tumor resection or nephrectomy,all of them recovered well without recurrence.The average follow-up period was 67(9-110)months.Erythrocyte level of the child with polycythemia normalized within 3 months post-operation.Conclusion As a rare tumor,metanephric adenoma is difficult to be diagnosed due to clinical characteristics and imaging features.It has a relatively favorable prognosis.Immunohistochemical findings are helpful in diagnosis.Chemotherapy is not required after surgery and imaging examinations of abdomen and pelvis should be performed as regularly during 3-year follow-up period.
