  iCCA PO
  Definition : Intrahepatic cholangiocarcinoma (iCCA) is a malignant intrahepatic epithelial neoplasm with biliary differentiation, arising in the liver periphery / proximal to the left and right hepatic ducts (WHO 2019)
  Microscopical synopsis
  iCCA consists of infiltrating well formed or cribriform glands in an abundant fibrous stroma (Liver Int 2019;39:7, Surg Pathol Clin 2018;11:403)
  Malignant glands are lined by cells with varying degrees of atypia and pleomorphism (...)

  PSC WKP PO
  Types
  neonatal sclerosing cholangitis
  auto-immune sclerosing cholangitis
  Microscopy synopsis
  "onion skin" fibrosis around affected medium sized bile ducts; smaller ducts rarely affected (except in small duct primary sclerosing cholangitis), meaning biopsy sampling rarely demonstrates this finding
  progressive atrophy of bile duct epithelium and obliteration of the lumen, leaving a fibrous scar
  ductular reaction and cholestasis may (...)
