Area of Science:

  • Oncology
  • Pathology
  • Gynecologic Oncology

Background:

  • Wilms' tumor is a rare kidney cancer typically diagnosed in children.
  • Extrarenal Wilms' tumor (EWT) is exceptionally rare, with most cases occurring outside the kidney.
  • EWT in the female genital tract is exceedingly uncommon.

Observation:

  • A case of EWT presenting as an ovarian mass in a 56-year-old woman is described.
  • Histological examination revealed glomeruloid and tubular structures within undifferentiated epithelial nests.
  • No teratomatous components were identified in the tumor.

Findings:

  • This case represents the oldest patient reported with EWT in the medical literature.
  • The tumor occurred in the ovary, a rare site for EWT.
  • The histological features were consistent with Wilms' tumor, despite the extrarenal location and patient's age.

Implications:

  • This case expands the known age range for EWT.
  • It highlights the importance of considering EWT in the differential diagnosis of ovarian masses, even in post-menopausal women.
  • Further research into the pathogenesis and behavior of EWT in adults may be warranted.
