Neuroblastoma can rarely present as a solid intrarenal mass in children, mimicking Wilms tumor. Histologically identical undifferentiated neuroblastoma in six cases highlights this diagnostic challenge and potential for misdiagnosis.

Area of Science:

  • Pediatric Oncology
  • Nephropathology
  • Diagnostic Imaging

Background:

  • Solid intrarenal neoplasms in pediatric patients are predominantly Wilms tumors.
  • Neuroblastoma, a common pediatric malignancy, typically arises in the adrenal medulla or sympathetic ganglia.
  • Rare presentations of neuroblastoma within the kidney can occur, posing diagnostic challenges.

Purpose of the Study:

  • To describe cases of intrarenal neuroblastoma that were initially suspected to be Wilms tumors.
  • To highlight the histological similarities between intrarenal neuroblastoma and Wilms tumor.
  • To emphasize the importance of considering neuroblastoma in the differential diagnosis of pediatric intrarenal masses.

Main Methods:

  • Review of six pediatric cases with solid intrarenal neoplasms.

  • Histopathological examination of tumor samples.
  • Clinical correlation and outcome assessment.

    • Main Results:

    • All six cases presented with solid intrarenal masses.
    • Histological analysis revealed undifferentiated neuroblastoma in all cases.
    • Patients experienced rapid clinical deterioration, suggesting aggressive disease.

    Conclusions:

    • Intrarenal neuroblastoma can mimic Wilms tumor on initial presentation.
    • Histological confirmation is crucial for accurate diagnosis.
    • Early recognition of intrarenal neuroblastoma is vital for appropriate management and improved outcomes.
