Definition / general
  • Formerly called lipopeliosis
  • Preservation injury causes their death with loss of fat
  • Fat droplets accumulate to form fat globules that mimic dilated sinusoids (week 1), then are surrounded by macrophages and cleared by 3 - 4 weeks
Pathophysiology
  • Steatotic hepatocytes are present in donor liver
Microscopic (histologic) description
  • Apparent sinusoidal engorgement by large fat globules, although fat globules are actually outside sinusoids when collagen IV immunostaining is performed
  • Variably damaged hepatocytes
