Definition / general
  • Kidney is main route for lead removal from body; lead is absorbed by proximal tubular cells, binds to specific proteins; with acute lead nephrotoxicity in dose-response relationship (Zhonghua Lao Dong Wei Sheng Zhi Ye Bing Za Zhi 2010;28:170), these lead-protein complexes are seen as intracellular inclusions (eMedicine: Lead nephropathy [Accessed 28 December 2017])
  • Due to occupational (electric storage battery makers, foundrymen, jewelers, painters, welders) or environmental causes (children eating lead pain, water in lead pipe systems, lead earthenware, moonshine liquor)
  • Lead exposure damages central and peripheral nervous system, GI tract and kidney
Microscopic (histologic) description
  • Tubular atrophy and interstitial fibrosis
  • Tubular inclusions are eosinophilic and intranuclear or cytoplasmic, acid-fast and red with Giemsa stain
  • Arteriolar disease similar to nephrosclerosis
  • Tubules disappear in chronic disease; no inflammation

  • Inclusions are lead-protein complex that appear as compact cores surrounded by loose meshwork of fibrils
