IPLab:Lab 3:Foreign Body Granuloma

• 

  This is a low-power photomicrograph of lung and pleura. There is some hemorrhage in this tissue (arrows), probably the result of surgery or the gunshot wounds.

• 

  This higher-power photomicrograph demonstrates the small focal cellular lesions (arrows) found throughout the parenchyma of the lung.

• 

  A higher-power photomicrograph of these granulomas reveals that they surround blood vessels (note the red blood cells within the lumen) (arrow).

• 

  This is a photomicrograph of lung taken under light that is partially polarized to demonstrate the birefringent particles within the granulomas (1). Also, at this magnification one can better appreciate that these granulomas are adjacent to blood vessels (2).

• 

  This is a fully-polarized view of lung showing numerous birefringent particles.
