Paediatric renal tumours and masses

Dr Owen Kang and A.Prof Frank Gaillard et al.

Paediatric renal tumours and masses are another group of diseases (just like cystic renal diseases in both the adult and child) that are bewildering in their number, nomenclature and overlapping findings.

Commoner lesions
  • Wilms tumour: common in older children 1-8 years old
  • mesoblastic nephroma
    • most common neonatal renal mass; benign hamartoma but is nonetheless resected as sarcomatous degeneration is a concern
    • local invasion of perinephric tissues is also seen; when diagnosed and treated before 3 months of age prognosis is good
  • nephroblastomatosis:  congenital condition with persistent metanephric blastema in the kidneys of infants and children 1
Adjacent to kidney
  • neuroblastoma: not a tumour of the kidney, but of the adrenal and other neural crest tissues, it needs to be differentiated from a Wilms tumour.  Distinguishing features include
    • calcification more common (90% vs 15%)
    • encases vascular structures but does not invade them
    • younger age group (<2 years of age)
    • usually bilateral
    • poorly marginated
    • more common to have  extension into chest
    • see distinguishing between neuroblastoma and Wilms tumour
