title: [Prenatal diagnosis of congenital mesoblastic nephroma. A case report].
abstract: Antenatal ultrasounds allow the detection of renal tumors, especially renal mesoblastic nephromas, but only the pathological analysis of the surgical specimen can confirm this diagnosis postnatally.
  
  
  METHODS
  We report the prenatal discovery of a mesoblastic nephroma because of premature labour. Postnatal early surgery was decided because of possible complications in this premature infant. Histology revealed mesoblastic nephroma.
  
  
  CONCLUSIONS
  We point out the diagnostic elements of congenital mesoblastic nephroma, especially in what is related to arterial hypertension and hypercalcemia, histology and cytogenetics.
