File:IPLab5Antitrypsin5.jpg
This is a low-power photomicrograph from an area of the lung without significant hemorrhage. The enlarged, emphysematous air spaces are easily appreciated.
File:IPLab5Antitrypsin4.jpg
This is a gross photograph of the bronchi and lungs. Note the hemorrhage in the bronchi and in the lung parenchyma.
File:IPLab5Antitrypsin2.jpg
This is a gross photograph of the cut sections of lung from this case. The lung parenchyma is markedly hemorrhagic and consolidated. Again the hemorrhage makes it difficult to appreciate the emphysematous changes.
File:IPLab5Antitrypsin1.jpg
This is a gross photograph of the lungs from this case. The rough friable material on the surface of the lung (arrows) is fibrinous exudate and fibrous tissue. This reaction on the surface of the lung is due to the recent surgery. The emphysematous cha...

File:IPLab5PolycysticKidney11.jpg
This is a higher-power photomicrograph of liver cyst. These cystic structures are lined by biliary epithelium.
File:IPLab5PolycysticKidney10.jpg
This is another photomicrograph of liver demonstrating the histologic appearance of these cysts. These cystic structures are associated with the biliary tree.
File:IPLab5PolycysticKidney9.jpg
This photomicrograph of liver demonstrates the histologic appearance of these cysts.
File:IPLab5PolycysticKidney8.jpg
This is a gross photograph of the liver from this patient. Multiple cysts can be seen on the surface of this liver (arrows).
File:IPLab5PolycysticKidney7.jpg
This high-power photomicrograph shows abnormal glomeruli (arrows) and some tubules.
File:IPLab5PolycysticKidney6.jpg
This is a higher-power photomicrograph of polycystic kidney showing the edge of a large cyst (1). In this section there are numerous tubules and dilated collecting ducts (2) that are filled with the same red proteinaceous material as the larger cysts.
File:IPLab5PolycysticKidney5.jpg
This is another low-power photomicrograph of an H&E-stained section from this polycystic kidney. Again note the large cystic structures (arrows)and the fibrous connective tissue throughout this section.
File:IPLab5PolycysticKidney4.jpg
This is a low-power photomicrograph of an H&E-stained section from this polycystic kidney. Note the large cystic structures (1), the few residual glomeruli (2), and the fibrous connective tissue throughout this section.
File:IPLab5PolycysticKidney3.jpg
This is a gross photograph of a cut section from one of these polycystic kidneys. Note that the renal parenchyma is almost completely replaced by cystic structures.

File:IPLab5PolycysticKidney2.jpg
This is a gross photograph of the kidneys from this case. Note that both kidneys contain multiple large cysts (arrows).

File:IPLab5Neurofibromatosis8.jpg
This is a high-power photomicrograph of the cells in the neurofibroma.
File:IPLab5Neurofibromatosis7.jpg
This higher-power photomicrograph of the neurofibroma shows more clearly the elongated cells (primarily Schwann cells) that make up this tumor.
File:IPLab5Neurofibromatosis6.jpg
This is a higher-power photomicrograph of the neurofibroma demonstrating the loose pattern of elongated cells making up the tumor mass.
File:IPLab5Neurofibromatosis5.jpg
This is a higher-power photomicrograph of the neurofibroma (1) with the overlying skin (2).
File:IPLab5Neurofibromatosis4.jpg
This is a low-power photomicrograph of a subcutaneous neurofibroma (1). Note the increased pigmentation in the skin (2).
File:IPLab5Neurofibromatosis3.jpg
This is a closer view of neurofibromas on the skin.
File:IPLab5Neurofibromatosis2.jpg
This is another view taken at autopsy demonstrating the neurofibromas. Some lesions can be seen as subcutaneous swellings (arrow) and others form pedunculated masses. Most are hyperpigmented.
File:IPLab5Neurofibromatosis1.jpg
This photograph, taken at autopsy, demonstrates the distribution of neurofibromas on the skin of this patient.

This is a cut surface of the same tissue seen in the previous slide. Note the marked nodular pattern. The paler-staining areas between the round nodules represent fibrous connective tissue.

File:IPLab2FattyChange11.jpg
This gross photograph of liver demonstrates severe nodular cirrhosis. Note the extensive scarring of the capsule and the nodular projections of tissue through the uncut capsule in this tissue. The green color is due to the accumulation of bile pigment.
File:IPLab2FattyChange10.jpg
This is a low-power photomicrograph of liver stained with a trichrome stain. In this section, connective tissue stains green (arrows) and hepatic parenchymal cells are red. Note that many of the parenchymal cells have clear spaces indicating fatty dege...
File:IPLab2FattyChange9.jpg
This photomicrograph of the liver is from another patient with a history of alcohol use. There are some clear vacuoles indicating fat droplets (1) and there are numerous red-staining granular deposits within the cytoplasm of hepatocytes (2)--this is al...
File:IPLab2FattyChange8.jpg
An oil red O stain for fat was performed on a frozen section of this liver tissue. The red droplets represent fat in the tissue which is typical of fatty degeneration in the liver. By using frozen sections the tissues do not have to be dehydrated throu...
File:IPLab2FattyChange7.jpg
A high-power photomicrograph of the liver parenchyma shows that each individual liver cell is filled with a large, clear droplet which represents the space remaining after lipid was dissolved by the dehydration procedure used to embed the tissue. '''No...
File:IPLab2FattyChange6.jpg
Another view at the same power illustrates the proliferation of bile ducts in the interlobular and perichordal regions (arrows).
File:IPLab2FattyChange5.jpg
This higher-power photomicrograph of the centrilobular area gives the appearance of fatty tissue, as indicated by many empty spaces. Very few normal liver cells can be seen in this slide. A few more normal-appearing hepatocytes are present at the left ...
File:IPLab2FattyChange4.jpg
A higher-power photomicrograph illustrates more clearly the inflammatory cells (arrows) around the portal areas.
File:IPLab2FattyChange3.jpg
Another low-power photomicrograph illustrates again the pale, washed-out appearance of this tissue. Notice the numerous holes throughout the tissue. There are accumulations of inflammatory cells (arrows) around portal tracts.
File:IPLab2FattyChange2.jpg
This low-power photomicrograph of liver illustrates a very pale-staining section with a uniform appearance throughout the section.
