Definition / general
  • Endothelial injury with vascular necrosis
  • Existence as a separate lesion from fetal thrombotic vasculopathy (FTV) is debated by some
  • Associated with maternal hypertension, fetal neurologic injury, growth restriction, tissue hypoxia and increased perinatal morbidity / mortality
  • Etiology is unknown
Microscopic (histologic) description
  • Vascular wall injury with extravasated red cells, endothelial / medial hyperplasia, red cell fragmentation and hemosiderin deposition
  • Changes similar to intrauterine fetal demise but are focal rather than diffuse
  • May be accompanied by chronic villitis, chorionic vascular thrombosis, erythroblastosis, villous fibrosis, infarction and evidence of meconium exposure
