Definition / General
  • Assorted group of disorders that share the common feature of glomerular cysts
  • Classified based on association with other syndromes into four groups: familial GCKD, hereditary GCKD associated with ADPKD / ARPKD / tuberous sclerosis, syndromic but nonhereditary GCKD, sporadic and acquired GCKD
  • Acquired includes associated with maternal phenacetin use during pregnancy (Arch Pathol Lab Med 1977;101:462) and hemolytic-uremic syndrome (Pediatr Nephrol 2001;16:557); syndromic includes hypomelanosis of Ito (Pediatr Nephrol 2008;23:1183)
