Definition / general
  • Neoplastic disorder of Langerhans cells, formerly called histiocytosis X
  • Causes 15% of sclerosing cholangitis in children, usually affects intrahepatic bile ducts
  • Remarkable selectivity for bile ducts, eventually causes biliary cirrhosis
  • May only affect liver; also affects lymph nodes, skin
Laboratory
  • Gamma glutamyl transpeptidase is sensitive indicator of liver infiltration in children with LCH
Case reports
  • 65 year old woman with sclerosing cholangitis 4 years after diagnosis of Langerhans cell histiocytosis (Hepatol Int 2010;4:653)
Microscopic (histologic) description
  • Langerhans cells may surround bile ducts and infiltrate sinusoids in nodules or diffusely
  • Associated with cirrhosis, sclerosing cholangitis, eosinophils, lymphocytes, plasma cells and neutrophils (Mod Pathol 1999;12:370)
