Area of Science:

  • Pediatric Oncology
  • Nephrology
  • Pathology

Background:

  • Renal oncocytoma is a rare, benign kidney tumor typically affecting adults.
  • Bilateral and multifocal presentations of renal oncocytoma are exceptionally uncommon, particularly in pediatric cases.

Observation:

  • A 12-year-old female presented with significant left kidney enlargement (massive renomegaly).
  • Radiological imaging revealed extensive disease and bilateral cystic kidneys.
  • The patient underwent a left nephrectomy for diagnosis and management due to tumor size and extent.

Findings:

  • Histological examination confirmed a diagnosis of multifocal renal oncocytoma.
  • This diagnosis is notable given the rarity of bilateral and multifocal occurrences in childhood.

Implications:

  • Highlights the importance of considering rare renal tumors in pediatric differential diagnoses.
  • Suggests the need for careful histological evaluation in pediatric cases presenting with complex renal masses.
  • Contributes to the limited literature on pediatric multifocal renal oncocytoma, aiding future research and clinical understanding.
