    • Fibrinous Transudate
    • increase in fibrin causes this shaggy coating. can occur between membranes and decrease mobility, such as in fibrinous pericarditis
    • Serous Exudate
    • "like serum" - fluid filled cavity
    • this one is following a burn
    • Note that it's pretty much empty - use this to identify serous
  1. Vascular Congestion and Stasis
    • Large vesicle - bullae. most likely serous exudate
    • blackness - eschar
    • subcutaneous bullae
    • normally contains an exudate. this one looks like it's purulent (good deal of fibrin in there. Purulent is fibrinous + PMNs)
  2. Shaggy appearance up top indicates fibrinous exudate over the surface (in this case, of the heart). Due to the breaking of fine adhesions b/w visceral and parietal pericardium
  3. Pseudomembrane of necrotic, inflammatory cells and fibrous jazz accumulated over the epithelial glands
  4. Pale area is fibinous exudate that has caused the lung to consolidate with the darker, aerated region
  5. Neutrophils (left) and fibrin (light pink, "chicken wire") within the alveolar spaces. Pneumonia
    • Purulent Exudate is masking the gyral pattern of the brain.
    • Also see hyperemia
    • Furuncle - skin abcess
    • Abscess with skin ulceration

    A bunch of these is a carbuncle. you'd see swelling and erythemia of the entire skin
