This immunofluorescent photomicrograph of a glomerulus from a case of acute poststreptococcal glomerulonephritis shows a granular immunofluorescence pattern consistent with immune complex disease. The primary antibody used for this staining was specifi...
File:IPLab6GN7.jpg
This is a photomicrograph of a glomerulus from another case with acute poststreptococcal glomerulonephritis. In this case the immune complex glomerular disease is ongoing with necrosis and accumulation of neutrophils in the glomerulus.
File:IPLab6GN6.jpg
This is an electron micrograph of subepithelial granular electron dense deposits (arrows) which correspond to the granular immunofluorescence seen in the previous image.
File:IPLab6GN5.jpg
This is an immunofluorescent photomicrograph of granular membranous immunofluorescence (immune complex disease). The antibody used for these studies was specific for IgG.
File:IPLab6GN4.jpg
This is a photomicrograph of interstitial and vascular lesions in end stage renal disease.
File:IPLab6GN3.jpg
This is a higher-power photomicrograph of hyalinized glomeruli (1) and glomeruli with thickened basement membranes (2).
File:IPLab6GN2.jpg
This is a higher-power photomicrograph of hyalinized glomeruli (arrows) and glomeruli with thick basement membranes.

File:IPLab6TB6.jpg
This is a high-power (oil immersion) photomicrograph of granuloma stained with an acid-fast stain. Mycobacterium tuberculosis bacilli stain red.
File:IPLab6TB5.jpg
High-power photomicrograph of a TB granuloma with multinucleated giant cells adjacent to an area of caseous necrosis (to the left).
File:IPLab6TB4.jpg
This is a higher-power photomicrograph of a TB granuloma. The area of caseous necrosis is on the left side of the image, there are multinucleated giant cells and epithelioid macrophages throughout the remainder of the tissue.
File:IPLab6TB3.jpg
This is a higher-power photomicrograph of a TB granuloma. Note the eosinophilic material in the center of this granuloma (caseous necrosis) and the epithelioid macrophages and giant cells around the periphery.
File:IPLab6TB2.jpg
This is a low-power photomicrograph of lung tissue with multiple circumscribed nodules - granulomas (arrows).
File:IPLab6TB1.jpg
This is a photograph of a section of lung with an apical lesion. This lesion represents an old healed lesion from Mycobacterium tuberculosis infection.

File:IPLab6Scleroderma5.jpg
This is a gross photograph of the heart from this case. There is thickening of the left ventricular wall and some thickening of the right ventricle as well.
File:IPLab6Scleroderma4.jpg
This is a closer view of the cut section of lung from this patient showing the extensive fibrosis and the severe emphysematous change.
File:IPLab6Scleroderma3.jpg
This is a closer view of the cut section of lung from this patient. Note the extensive fibrosis and the severe emphysematous changes.
File:IPLab6Scleroderma2.jpg
This is a gross photograph of a cut section of one lung from this patient. Note the extensive fibrosis lower lobe (arrows).
File:IPLab6Scleroderma1.jpg
This is a gross photograph of cut section of the lungs from this patient. Note the extensive fibrosis of the lung parenchyma.

File:IPLab6PAN13.jpg
This is a high-power photomicrograph of the affected vessel in the heart. The vessel lumen is completely occluded.
File:IPLab6PAN12.jpg
This is a higher-power photomicrograph of the affected vessels in the heart (arrows). There are areas of fibrosis (old infarcts) in the myocardium adjacent to these affected vessels.
File:IPLab6PAN11.jpg
This is a low-power photomicrograph of the heart. There are areas of fibrosis in the myocardium (arrows). Note that the large epicardial coronary artery is normal.
File:IPLab6PAN10.jpg
This is a higher-power photomicrograph of the affected vessel from the previous image. The vessel wall is infiltrated with inflammatory cells and the vessel lumen is completely occluded (arrow).
File:IPLab6PAN9.jpg
This is a low-power photomicrograph of the adrenal gland. There is an area of necrosis in the adrenal (1) and an affected vessel adjacent to the adrenal (2).
File:IPLab6PAN8.jpg
This is a high-power photomicrograph of a small vessel with a rim of fibrinoid necrosis (arrow).
