title: Pathology of the liver.
abstract: Traditional anatomic pathology studies and molecular investigations both contributed to the breadth of current information in the field of liver pathology this year. Techniques such as reverse transcription polymerase chain reaction can identify recurrence of hepatitis C virus infection in the liver as early as 5 days after transplantation. Chronic rejection after transplantation may be characterized not only by ductopenia but also by loss of portal tract hepatic artery branches. There are many diseases of small bile ducts in adults, and idiopathic adulthood ductopenia has been identified in extended family members. Adverse reactions to drugs may precipitate their removal from the pharmacopoeia, such as the many cases reported of severe bridging and submassive necrosis due to troglitazone (a thiazolidinedione antidiabetic agent). Several publications highlighted the association of hepatitis C virus infection with lymphoproliferative diseases and, newly, with cholangiocarcinoma.
