Ascaris suum
  • Ascariasis
  • 'milk spot' liver
  • pigs
  • common incidental finding at post mortem examination
  • affected livers are condemned at meat inspection
Gross
  • initial haemorrhagic tracts through the liver attributed to the migration of ascarid larvae
  • later stages show fibrosis of these tracts as poorly defined, diffuse, white spots on the capsular surface
Microscopically
  • initial haemorrhage and necrosis of parenchyma along the tracts
  • later repair by fibrous tissue at foci
  • inflammatory cell response contains many eosinophils, as well as lymphocytes and macrophages
