General
=========================================================================

● Usually irreversible injury of hepatic allografts, likely secondary to ischemic damage to hepatocytes or direct immunologic damage to bile ducts with total loss (vanishing bile duct syndrome)
● May have insidious onset with no acute component

Micro description
=========================================================================

Vanishing bile duct syndrome: loss of intrahepatic bile ducts, minimal portal inflammation
Obliterative endarteritis: occlusion by subintimal fibrosis and foam cell change in large and medium sized hilar hepatic arteries and portal vein and distal branches near hilum
● Also associated ischemic changes of centrilobular ballooning degeneration, pericellular fibrosis and possibly cirrhosis
● Changes more variable in portal vein
● Pathognomonic arterial changes are rarely present in needle biopsies

Differential diagnosis
=========================================================================

● Recurrent primary sclerosing cholangitis (Liver Transpl 2006;12:S68)
● Recurrent hepatitis C (Liver Transpl Surg 1997;3:398, Hum Pathol 2009;40:92, Adv Anat Pathol. 2009;16:97)
