Q

Morphology of cute ulcer

A

intense polymorphonuclear infiltration and vascular dilation in the margins of the defect.

23
Q

chronic ulcer morphology

A

fibroblastic proliferation
scarring
accumulation of lymphocytes, macrophages, and plasma cells.

24
Q

Imflmmtion where the exudate of fibrin, pus, cellular debris, and mucus forms a pseudomembrane on the surface of the ulcers.

A

Pseudomembranous Inflammation

25
Q

inflammation caused by Clostridium difficile

A

pseudomembranous colitis

26
Q

Four outcomes of acute inflammation

A

resolution
healing by fibrosis
abscess formation
chronic inflammation

27
Q

Outcome that involves the restitution of normal architecture and function where the connective tissue framework of the tissue is intact

A

resolution

28
Q

Outcome known as scar formation occurs when there is substantial damage to the connective tissue framework and/or the tissue lacks the ability to regenerate specialized cells

A

Healing by fibrosis

29
Q

Despite the loss of some specialized cells and some architectural distortion by fibrous scar, structural integrity is reestablished.

A

Healing by Fibrosis

30
Q

Healing by fibrosis which occurs quickly with a small amount of granulation tissue

A

healing by primary intention

31
Q

Healing by fibrosis that is large and filled with blood clot and a variable amount of tissue debris.

A

healing by secondary intention

32
Q

Takes place when the acute inflammatory reaction fails to destroy/remove the cause of tissue damage and continues, and is common in the case of infection by pyogenic bacteria

A

Abscess formation

33
Q

Outcome that results following acute inflammation when an injurious agent persists over a prolonged period, causing concomitant tissue destruction.

A

chronic inflammation

34
Q

The hallmark features of chronic inflammation

A

ongoing tissue damage

35
Q

ongoing tissue damage is often caused by

A

the inflammatory cells in the infiltrate
a chronic inflammatory infiltrate
fibrosis

36
Q

Chronic inflammation can be caused by one of the following three ways:

A

Persistent infections
Immune-mediated inflammatory diseases
Prolonged exposure to potentially toxic agents, either exogenous or endogenous

37
Q

Caused by microorganisms that are difficult to eradicate like mycobacteria and certain viruses, fungi, and parasites

A

Persistent infections

38
Q

Organisms that are difficult to eradicte often evoke an immune reaction called_________ and the inflammatory response takes a specific pattwrn called

A

delayed-type hypersensitivity, granulomatous reaction.

39
Q

chronic inflammation cause that is group of diseases that are caused by excessive and inappropriate activation of the immune system

A

Immune-mediated inflammatory diseases

40
Q

conditions where immune reactions develop against the individual’s own tissu

A

autoimmune diseases

41
Q

Examplew of toxic agents, either exogenous or endogenous that cause chronic imflammation

A

silica causing silicosis

endogenous toxic lipid component causeing atherosclerosis

42
Q

3 Morphologic Features of Chronic Inflammation

A

Mononuclear Cell Infiltration
Tissue Destruction or Necrosis
Proliferative Changes

43
Q

2 Types of Chronic inflammation

A

Non-specific

Specific

44
Q

An example of this inflammation is chronic ulcer when the irritant substance produces a reaction with formation of granulation tissue and healing by fibrosis

A

Non specific

45
Q

Inflammation where the injurious agent causes a characteristic histologic tissue response like in tuberculosis

A

Specific

46
Q

Two classifications of inflammation according to descriptive histologic features

A
  1. Chronic non-specific inflammation

2. Chronic granulomatous inflammation

47
Q

This is characterized by non-specific inflammatory cell infiltration (e.g. chronic osteomyelitis, lung abscess)

A

Chronic non-specific inflammation

48
Q

This is characterized by formation of granulomas (e.g. tuberculosis, leprosy, syphilis, etc)

A

Chronic granulomatous inflammation

49
Q

A distinctive pattern of chronic inflammation encountered in a limited number of infectious
and some non-infectious conditions.

A

Granulomatous Inflammation

50
Q

This is a cellular attempt to contain an offending agent that is difficult to eradicate, involving strong activation of T lymphocytes leading to macrophage activation causing injury to normal tissue

A

granuloma

51
Q

granuloma morphology

A

1 mm tiny circumscribed lesiom
composed predominantly of modified macropahages (epitheliod cells)
rimmed at the periphery by lymphoid cells

52
Q

Granuloma that have a large mass of cytoplasm containing 20 or more small nuclei arranged either peripherally.

A

Langhans-type giant cell

53
Q

Granuloma that have a large mass of cytoplasm containing 20 or more small nuclei arranged either haphazardly.

A

foreign body-type giant cell
