Tutorial Name: Irreversible Cell Injury
ConceptName: Liquefactive necrosis
Slide Name: Staphylococcal Pneumonia (high)

Image Description: Higher magnification from the area of the abscess shows bacteria (the group of small blue dots), fibrin, necrotic tissue, neutrophils, and macrophages within the abscess. Note that the abscess locally destroys the alveolar septa.

 
Structures Structure Descriptions
proteinaceous material w/ inflam cells The lung parenchyma surrounding the abscess is hemorrhagic and edematous (area at right of image). The edema fluid is pink due to high protein content.
necrotic debris w/ inflamm. Cells The dominant inflammatory cells are neutrophils - these cells cannot be identified at this power.
bacteria Colonies of staphylococci within the abscess stain dark blue with H&E.
