Idiopathic adulthood ductopenia

In 1981, a 26 year old man occasionally demonstrated elevated serum transaminase concentrations. He had no history of medication, or a personal or family history of jaundice, except for prolonged physiological jaundice as a neonate. Serum hepatitis B surface antigen, hepatitis C virus antibody and anti-mitochondrial antibody were absent. A wedge biopsy specimen revealed ductular proliferation, mild inflammation of the portal area and disappearance of bile ducts from 80% of the portal tracts. Serial sections demonstrated a vanishing bile duct. Endoscopic retrograde choledochopancreatography, portography and arteriography demonstrated no abnormalities. In 1994, the patient died of hepatic failure following a 12 year observation period. He was subsequently diagnosed with idiopathic adulthood ductopenia on the basis of the criteria proposed by Ludwig.
