General and Systemic Histopathology, C601&C602
    Slide 76: Lung with tuberculosis
    Look carefully at the lung tissue for the little pink areas of caseous necrosis. These are the areas of tubercular infection. They don't show a well developed granuloma architecture, but you'll see the evolving features and should have no trouble finding the giant cells.

    See this slide with the virtual microscope.

    This picture details two of the giant cells associated with one of the granulomas. You can see the peripheral array pattern of the nuclei in the larger one. The age of this slide has contributed to the "hot pink" staining quality. Other than the accentuation of the eosinophilic property of the stain, this slide is very good representation of the tubercular process.
