Inflammation Healing III granulation tissue

Inflammation and Healing images
Show Answers:

  1. Granulation Tissue
    • Organization
    • The fibrinous exudate (up top) is healing. can tell by the parallel vessels
    • Granulation Tissue
    • Lots of Inflammatory cells, blood vessels and fibroblasts
    • Organization of Exudate
    • Look for the angiogenesis - this purulent exudate is in the process of organization.
    • high power would show fibroblasts, macrophages and inflammatory cells
    • top right is myocardium, lower left is granulation tissue
    • Can tell this isn't a granuloma because of: 1) vessels 2) no giant cells 3) no lymphocyte boundary
  2. RBCs a giveaway that this is granulation tissue
  3. Thromboemboli undergoing organization from vessel out
  4. Healing by first intention (primary union)
  5. Myocardial scar w/ trichrome stain to show collagen (so this healed by repair)
  6. What kind of repair happened here?
    The nodules due to cirrhosis are due to fibrosis and regeneration
  7. What is this formation called? What type of collagen?
    • Keloid
    • Early - Type III
    • Late - Type I
  8. Recanalized Thrombus
