1
Q

T or F. Inclusion bodies due to viral infections can occur within the cytoplasmic space and can occur within nuclei?

A

True — Viruses need replication machinery present in the nucleus — Lead to Negri Bodies

2
Q

Herpes Virus builds up in both locations as well.

A

CMV — Cytomegalovirus— “Big Cell” — Owl’s Eye — or Cowdry Type A inclusions. — nuclear inclusions and granular

3
Q

Cellular Atypia is not a histopathologic feature of Dysplasia? T or F?

A

False

4
Q

All accumulations are the result of either a cell’s rate of production exceeding clearance or else the failure to metabolize an endogenous substance.

A

False — Coal Dust, Pollution, Melanoma

5
Q

Dysplasia is often a precursor to malignant transformation. T or F?

A

True

6
Q

With amyloidosis the heart liver or kindness are not common sites.

A

False

7
Q

A feature shared in common by both accumulations and adaptations is that both can arise from physiological and pathologic stimuli.

A

True

8
Q
A
9
Q
A

Both

10
Q
A

Cytomegalovirus

11
Q
A

Hypertrophy — “Box car Changes”

12
Q
A

Systolic

13
Q

Features of Dystrophic Calcification

A

Atrioventricular closing shut — lub

Aortic Valve and Pulmonary Artery Close — Dub

Lub Shuh Dub — Systolic Murmur — blood is having a hard time getting out of the ventricular chamber and into the aorta.

If you have dystrophic calcification it will have a hard time getting out of the aorta.

14
Q
A

Hyperplasia.

Lymphocyte hyperplasia which are reacting to some sort of infection.

15
Q
A

Prussian blue stains — stains iron.

Build up of iron in liver.

16
Q
A

High Ferritin associated with high total body Iron levels.

Longer Prothrombin time means blood is taking longer to clot than normal.

Liver makes clotting Factors

17
Q
A

Primary Hemochromatosis. (Answer) Inherited form — autosomal recessive — Genetic Form

Secondary Hemochromatosis — Multiple Transfusions — Iron buildup (sometimes called Hemosiderosis)

Hemosiderosis — There’s no anemia. Sometimes only refers Iron buildup as a result of macrophage activity.

18
Q
A

Excessive absorption of iron from the gastrointestinal tract.

19
Q
A

Cardiac Biopsy from a middle aged man.

Hypo-chromatic. Less organization.

Deposits of Amyloids.

20
Q
A
21
Q
A

You need polarizing light/filter to see the congo red stain show the apple green color.

Beta pleaded structures form fibrils.

22
Q
A

Physical Conformation — beta pleaded structure.

Congo red stain binds to meshwork of the beta pleaded structure.

23
Q

From among the following conditions the one responsible for the abnormalities seen in the photomicrographs seen in this conditions

Chronic Inflammation — rheumatoid arthritis

Aging

Plasma cell tumor that produces immunologlobulin light chain

A renal disease that requires chronic dialysis

Not able to be determined given the limited amount of information.

A

Not able to be determined given the limited amount of information. — Amyloid is produced by many different causes.

24
Q

They autopsy reveials calcium deposits presents in normal appearing lung and kidney tissues.

A

Parathyroid Adenoma

25
Q

Increase in the number of parenchymal cells

A

Hyperplasia

26
Q

Consequence of persistent hypercalcemia is:

Metastatic calcification

Atherosclerosis

Amyloidosis

Dystrophic calcification

Hemochromatosis

A

Metastatic calcification

27
Q

Most common form of pathologic calcium

A

Dystrophic type

28
Q

Organ most commonly involved in amyloidosis is the:

Kidney

Heart

Liver

A

Kidney — action where a lot of amyloid deposition occurs in the glomeruli.
