Definition / general
  • Affects immunocompetent and immunocompromised
  • Usually acute self limited disease resembling infectious mononucleosis; rarely causes hepatic failure and death in patients with immunodeficiency syndromes
Laboratory
  • Elevated transaminase levels (80%), high EBV serum viral load; elevated bilirubin in only 7%
  • In some cases, infiltrating CD8+ T cells but not hepatocytes, are infected with EBV (Hum Pathol 2001;32:757)
  • May cause polymorphic B cell hyperplasia or lymphoma in immunocompromised
Microscopic (histologic) description
  • Predominantly sinusoidal infiltrate of atypical T lymphocytes with minimal necrosis
  • Presence of atypical lymphocytes may coincide with Downey cells in peripheral blood
  • Associated with viral associated hemophagocytic syndrome, with prominent erythrophagocytosis by sinusoidal Kupffer cells and portal histiocytes
  • Variable mitotic figures and small epithelioid granulomas
  • No bile duct injury or venulitis
