This gross photograph affords a closer view of the same aortic valve. Note the nodularity and thickening of this valve due to fibrosis and dystrophic calcification.
File:IPLab2Calcification7.jpg
A closer view of this same aortic valve (arrow) illustrates the nodularity and thickening of this valve. This valve would be extremely stiff and almost entirely immobile. This particular example of dystrophic calcification is associated with a degenera...
File:IPLab2Calcification6.jpg
Metastatic calcification is only one of two forms of pathologic calcification. Unlike metastatic calcification, dystrophic calcification does not require an increase in serum calcium levels. This is a gross specimen of a heart with dystrophic calcifica...

This photomicrograph demonstrates pulmonary alveoli with extensive calcium depositions (1) in the septa and protein accumulations (2) in the alveoli.
File:IPLab2Calcification4.jpg
This high-power photomicrograph of a blood vessel shows calcium deposits in the vascular wall (1) and proteinaceous material (2) (from edema) within some of the alveoli. The smooth muscle in the vessel wall has been almost completely replaced by calciu...
File:IPLab2Calcification3.jpg
A higher-power photomicrograph shows a blood vessel cut in longitudinal section (1). Several of the alveoli are filled with a pink-staining proteinaceous fluid (2) indicative of pulmonary edema. The alveolar septa and the wall of the blood vessel have ...
File:IPLab2Calcification1.jpg
This is a gross photograph of the cut section of the patient's lung showing evidence of severe metastatic calcification. The lung tissue has a rough, firm appearance with open airways.

File:IPLab2Atrophy10.jpg
This gross photograph shows a normal brain (left) and a brain from a geriatric patient (right). Note the decreased size, the narrowed gyri, and the widened sulci of the brain from this octogenarian. What is the cause of atrophy in this case?
File:IPLab2Atrophy9.jpg
The two kidneys in this slide are from the same patient. One kidney (1) is relatively normal, although increased in size due to compensatory hypertrophy. The other kidney (2) is very small with only rudimentary nodules of renal parenchyma. This kidney ...
File:IPLab2Atrophy8.jpg
These kidneys were removed from a patient who had blockage of one ureter leading to increased pressure in the renal pelvis. The increased pressure produced hydronephrosis (arrow) in one kidney. What is the cause of atrophy in this case?
File:IPLab2Atrophy7.jpg
In this gross photograph of kidneys and the abdominal aorta, there is narrowing of the left renal artery at its ostium from the aorta. This atherosclerotic narrowing of the renal artery causes reduced blood pressure in the kidney whose artery is affect...
File:IPLab2Atrophy6.jpg
In this slide, the atrophy of the tubules is extending to include the Rete testes (arrow) as well.
File:IPLab2Atrophy5.jpg
Peter Anderson uploaded a new version of "File:IPLab2Atrophy5.jpg": A seminiferous tubule is shown on the left containing remnants of spermatocytes (1). There are no mature sperm present. On the right-hand portion of the slide are remnants o
File:IPLab2Atrophy4.jpg
This is a higher-power photomicrograph indicating loss of testicular parenchymal tissue. There are very few recognizable spermatic cells in this tissue. The cluster of cells in the upper right is a focus of interstitial or Leydig cells (arrow). These c...

File:IPLab2Atrophy3.jpg
This is a higher-power photomicrograph of an atrophic testis. In this section there are seminiferous tubules with viable cells (1) although there are no visible spermatocytes. Other seminiferous tubules are completely acellular and have a pale pink hya...
File:IPLab2Atrophy2.jpg
This is a low-power photomicrograph of an atrophic testis. Attached to the testis are several vessels (arrow) which are part of the epididymis and the vas deferens.
File:IPLab2Atrophy1.jpg
This is a gross photograph of an atrophied testis (arrows).

File:IPLab2Metaplasia7.jpg
This is a photomicrograph of the trachea from a smoker. Note that the columnar ciliated epithelium has been replaced by squamous epithelium.
File:IPLab2Metaplasia6.jpg
A high-power photomicrograph of the squamous epithelium shows inflammatory cells in the subepithelial tissue and the formation of keratinized epithelium (arrows).
File:IPLab2Metaplasia5.jpg
In areas adjacent to the normal transitional epithelium, there are areas of epithelium (arrows) where the epithelial cells have the character of normal squamous epithelium as found in the dermis. However, squamous epithelium is not normal in the renal ...
File:IPLab2Metaplasia4.jpg
This is a higher-power photomicrograph of the junction of normal epithelium (1) with hyperplastic transitional epithelium (2).
File:IPLab2Metaplasia3.jpg
A higher-power view shows the junction of normal epithelium (1) with hyperplastic transitional epithelium (2). Note the inflammatory cells in the subepithelial tissue.
File:IPLab2Metaplasia2.jpg
his high-power photomicrograph demonstrates the transitional epithelium lining the renal calyx (1) and the junction (transition zone) to a thicker hyperplastic epithelium (2). Note the inflammatory cells and increased vascular response in the stromal t...
File:IPLab2Metaplasia1.jpg
This is a low-power photomicrograph showing the full cortical and medullary thickness of the kidney. Note that there is a dilated calyx containing some red blood cells in the center of the section (arrow). The cortex is markedly thin and has severe les...

File:IPLab2Hyperplasia9.jpg
This kidney was removed from another autopsy patient who had prostatic hyperplasia resulting in marked urinary retention and back-flow of urine from the bladder into the ureters and renal pelvis. The increased pressure inside the renal pelvis resulted ...

This is a higher-power photomicrograph of papillary folds of hyperplastic epithelium (arrows).
File:IPLab2Hyperplasia7.jpg
A higher-power view shows the papillary folds (arrows) produced by the hyperplastic epithelium projecting into the lumen of the gland. While these papillary folds project into the lumen of the gland, there is no extension through the glandular basement...
File:IPLab2Hyperplasia6.jpg
Cystic dilatation of glands is present in this photomicrograph. Notice the accumulation of secretory material inside the glands (arrows) and compression (thinning) of the lining epithelium.
File:IPLab2Hyperplasia5.jpg
Note these glands, which exhibit hyperplasia of the glandular epithelium. The infolding of the glandular epithelial cells forms papillary projections (arrows) into the lumen of the gland.
File:IPLab2Hyperplasia4.jpg
The dilated glands (arrows) make up the major portion of the prostate tissue and there is compression of the stroma.
File:IPLab2Hyperplasia3.jpg
This is a low-power photomicrograph showing hyperplastic prostate on the left (1) and normal prostate on the right (2). At this power, dilated glands are visible in the section of hyperplastic prostate.
File:IPLab2Hyperplasia2.jpg
This is a close-up of the prostate from this same patient. Note the nodularity of the tissue (1) and the enlargement of the gland. Enlargement of the prostate leads to compression of the urethra as it passes through (2) the gland.
File:IPLab2Hyperplasia1.jpg
This photograph shows the autopsy specimen from this patient. Included are kidneys (1), ureters (2), bladder (3) (which has been opened), and enlarged prostate (4). Note that the bladder mucosa has multiple trabeculae and the bladder mucosa is hyperemi...
