Definition / general
  • Cell mediated, potentially reversible
  • Either resolves or progresses to chronic graft rejection
  • Banff international consensus document criteria: mixed portal inflammation, cholangiolitis and endothelialitis (Hepatology 1997;25:658, Hepatology 2006;44:489)
Treatment
  • Cautious increase in immunosuppression (even if posttransplant lymphoproliferative disorder)
Microscopic (histologic) description
  • Portal infiltrate of lymphocytes and variable eosinophils and neutrophils that damage bile ducts and venous endothelium
  • No / minimal hepatocyte damage
  • Also loss of bile ducts, arteritis, central ischemic damage with ballooning degeneration and hepatocyte dropout
