Article Synopsis
  • - Malakoplakia is a rare inflammatory disease marked by specific cells and is particularly elusive when affecting the kidneys, as shown in a case involving a patient diagnosed in infancy.
  • - After 17 years, the patient experienced kidney issues leading to a diagnosis of focal segmental glomerulosclerosis (FSGS), but typical malakoplakia markers were not found in kidney biopsy samples.
  • - This case highlights that kidney damage from malakoplakia can evolve into FSGS and demonstrates how the disease can change over time, providing valuable insights into the long-term prognosis of renal parenchymal malakoplakia.
