title: A metanephric adenoma of the kidney associated with polycythemia: A case report.
abstract: Metanephric adenoma (MA) of the kidney is a rare and frequently benign tumor with a favorable prognosis that is often diagnosed following surgical treatment. In the present study, a 54-year-old female patient presented with complaints of intermittent right-flank pain and anterior abdominal pain occurring over 2 years and sporadic gross hematuria occurring over 3 months. Ultrasonography and computerized tomography imaging revealed a neoplasm lesion localized in the right kidney. Successful open approach radical nephrectomy was performed and post-surgical histopathological examination verified the lesion as a MA of the kidney. Radical nephrectomy, cryoablation or radiofrequency may used to treat MA and a selective panel of immunostains, including WT1, EMA and AMACR, may be useful for diagnosis.
