AI Article Synopsis

  • Most renal tumors in adults are carcinomas, typically requiring surgical treatment like nephrectomy or limited excision.
  • A 45-year-old woman with a renal tumor underwent a biopsy that revealed it was a benign metanephric adenoma, so no surgery was needed.
  • The text emphasizes the importance of immunohistochemistry for accurately diagnosing metanephric adenoma and highlights how biopsies can help determine the best treatment for renal tumors.

Article Abstract

Most renal tumors of the adult are carcinomas. Their treatment is surgical, consisting of limited excision or nephrectomy. In some instances, biopsy of the tumor can be performed in order to adapt treatment. We report the case of a 45 year-old woman presenting with renal tumor. A biopsy of the mass showed a metanephric adenoma. No surgical excision was performed because of the benignity of this tumor. Here we develop the interest of immunohistochemistry for differential diagnosis of metanephric adenoma and other "basophilic small cell tumors" of the kidney. We also put the stress on the growing role of biopsy of renal tumor allowing optimal treatment.
