File:IPLab3ForeignBodyGranuloma4.jpg
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 vesse...

File:IPLab3Tuberculosis4.jpg
This is a high-power photomicrograph of a granuloma. Note the necrotic core on the right (1), epithelioid macrophages (2), and Langhans’ type giant cells (3) at the periphery of the granuloma. Note also the small lymphocytes characterized by their di...
File:IPLab3Tuberculosis3.jpg
This is a photomicrograph of a tuberculosis granuloma. Note the central core of caseation necrosis (1) encircled by a rim of epithelioid macrophages and lymphocytes (2). Langhans’ type multinucleated giant cells are also present although they are dif...
File:IPLab3Tuberculosis2.jpg
This low-power photomicrograph of a section of lung reveals multiple large nodules (1) with pale eosinophilic centers surrounded by a rim of blue-staining nuclei. In addition to the large nodules, there are several smaller nodules throughout the slide ...
File:IPLab3Tuberculosis1.jpg
This is a gross photograph of a lung containing a nodular lesion at the lung apex (arrows). Note that the lesion appears solid and has a whitish coloration indicating considerable fibrous connective tissue. This is a healed granuloma due to primary tub...

File:IPLab3Sarcoidosis6.jpg
This is a higher-power photomicrograph of an asteroid body (arrow) inside of a multinucleated giant cell.
File:IPLab3Sarcoidosis5.jpg
This is a photomicrograph of a multinucleated giant cell (1). In the center of this foreign body-containing giant cell there is a small asteroid body (2). There is no functional significance to this asteroid body.
File:IPLab3Sarcoidosis4.jpg
This photomicrograph of a single granuloma illustrates the individual macrophages (arrows) which make up the bulk of this tissue. There is an absence of necrosis in the center of the lesions in this case.
File:IPLab3Sarcoidosis3.jpg
This is a photomicrograph of the small nodules (arrows) seen in the previous image. Close examination reveals that they are composed of large macrophages (epithelioid macrophages). These small granulomas form multiple series of reaction centers through...
File:IPLab3Sarcoidosis2.jpg
This photomicrograph of lymph node tissue illustrates a paucity of lymphocytes as well as numerous small, pale-staining nodules (arrows) throughout the tissue.
File:IPLab3Sarcoidosis1.jpg
This is a low-power photomicrograph of a lymph node. Note the rather pale-pink color of the tissue with dark-staining cells found in only a few scattered areas. These darker cells represent the original lymphocytes of this lymphoid organ.

File:IPLab3Bronchopneumonia7.jpg
This higher-power photomicrograph shows a central portion of an abscess. Note the absence of any parenchymal lung tissue in this section due to extensive neutrophilic infiltration with liquefaction necrosis of the parenchymal tissue. Masses of leukocyt...
File:IPLab3Bronchopneumonia6.jpg
This is a photomicrograph of another area in the lung showing a terminal bronchiole (1) in which the mucosal lining has been almost completely destroyed. There is extensive neutrophilic infiltration throughout this lung tissue.
File:IPLab3Bronchopneumonia5.jpg
This is a photomicrograph of lung tissue affected by bronchopneumonia. Note that the alveolar structure of this tissue, which is in the region of a terminal bronchiole (1), has been retained despite the massive infiltration of inflammatory cells. These...
File:IPLab3Bronchopneumonia4.jpg
This photomicrograph of the wall of an abscess (1) illustrates liquefaction necrosis in the center of the abscess (2). The remaining lung parenchyma (on the right side of the image) has extensive neutrophilic infiltration into the alveoli (3). This abs...
File:IPLab3Bronchopneumonia3.jpg
This is a low-power photomicrograph of lung with multiple focal lesions (1) throughout the tissue, some of which have a pale center indicating a loss of parenchymal tissue (2). This is typical of abscess formation in the lung and represents a form of l...
File:IPLab3Bronchopneumonia2.jpg
This is a closer view of the same lung tissue showing the individual small lung abscesses (arrows).
File:IPLab3Bronchopneumonia1.jpg
This gross photograph of lung illustrates multiple abscesses throughout the lung of this patient.

File:IPLab3LobarPneumonia8.jpg

File:IPLab3LobarPneumonia7.jpg
This is another photomicrograph of the junction of the pleura (1) with the lung parenchyma. Note the alveoli on the left (2) filled with PMNs, alveolar macrophages, and fibrin. The dark red-stained material (3) in the center and left portions of the sl...
File:IPLab3LobarPneumonia6.jpg
This photomicrograph of the lung shows the junction of the pleura (1) with the pneumonic lung parenchyma (2). Careful examination of the lung tissue at the right reveals the outline of alveolar structures in this tissue (arrows). The mass of cells infi...
File:IPLab3LobarPneumonia5.jpg
This is a photomicrograph of the interpleural space between the two lung lobules. Thickened pleura with extensive fibrin deposits is present on the left portion of the slide (1) and the right portion of the slide (2) contains the affected lung lobe. No...
File:IPLab3LobarPneumonia4.jpg
This low-power photomicrograph of the lung shows: (1) markedly thickened pleura, indicating an inflammatory process which has been present for several days; (2) a small wedge-shaped segment of normal lung which is somewhat compressed due to artifact; (...
File:IPLab3LobarPneumonia3.jpg
This is a gross photograph of the right lung from the patient in this case. This lung shows complete consolidation with a marked infiltration of neutrophils throughout the tissue giving the lung a whitish discoloration. Note the extensive black pigment...
File:IPLab3LobarPneumonia2.jpg
This is a cut section of a lung from the preceding image. Note the whitish discoloration of the lung tissue in the upper lobe (arrows) compared to the normal collapsed and pink staining lung lobe in the left-hand portion of the photograph. The white di...
File:IPLab3LobarPneumonia1.jpg
