External Anatomy of the Kidney

The kidneys are a pair of bean-shaped organs in the human body that play a critical role in maintaining overall health. They filter out waste products from the blood, regulate blood pressure, maintain electrolyte balance, and stimulate the production of red blood cells.
The kidneys are located in the retroperitoneal space on either side of the vertebral column, protected posteriorly by the 11th and 12th ribs. The right kidney sits slightly lower than the left owing to the presence of the liver...

Area of Science:

  • Pediatric Pathology
  • Oncology
  • Nephrology

Background:

  • Congenital mesoblastic nephroma (CMN) is a rare renal neoplasm in infants.
  • Accurate diagnosis is crucial due to potential for malignancy and challenging differentials.
  • CMN requires careful pathological evaluation for appropriate patient management.

Observation:

  • Presents three cases of congenital mesoblastic nephroma.
  • Highlights unusual morphological variations within CMN.
  • One case demonstrated concurrent renal dysplasia, a rare association.

Findings:

  • Morphological diversity in CMN can mimic other renal tumors.
  • Renal dysplasia in conjunction with CMN suggests complex developmental origins.
  • Detailed histopathological analysis is key to differentiating CMN from other pediatric renal masses.
