⑧ Describe ⇒ Microscopic section
1-Microscopic view of the edge of the infarct,
and necrotic cells in the infarct The necrotic cells show
preserved outlines with loss of nuclei
2-ischemic disease
3- Hematoxylin-eosin–staine
4-Coagulative necrosis

21. 1-A focus of inflammation containing numerous eosinophils.
2-infections (mainly parasitic)
-allergic diseases(asthma)

23. 1- microscopic section of the lung showing all three characteristic histologic
features:
(A) collection of chronic inflammatory cells
(B) destruction of parenchyma
(C) replacement by connective tissue (fibrosis, arrows).
2-tuberculosis
3- Chronic inflammation

29. 1- Fibrinous pericarditis
2- Deposits of fibrin on the pericardium(granulation process in chronic
inflammation)

31. 1-microscopic section of the lung showing Abscesses are localized
collections of pus
2-bronchopneumonia
3-Purulent inflammation.
4-liquefactive necrosis

33. (A) Granulation tissue showing numerous blood vessels, edema, and a loose
extracellular matrix containing occasional inflammatory cells.
(B) mature scar, showing dense collagen (stained
blue) and scattered vascular channels.
-Trichrome stain

37. 1- Low-power cross-section view of duodenal discontinuation epithelium
2-duodenal ulcer
3- acute inflammatory exudate

39. 1- section of leg showing A-External appearance of skin ulcers
B- arterial ulcer, with more extensive tissue necrosis
2- A-severe varicose veins
B-atherosclerosis of peripheral arteries
3-ischemia,neuropathy,prolonged compression of tissues against a bone

41. 1- section of the leg Tissue necrosis and failure to heal affect the lower
extremities,
particularly the feet
2-Diabetic ulcers
3- small vessel disease causing ischemia,neuropathy, systemic metabolic
abnormalities

49. 1- scar tissue grows beyond the boundaries of the original wound and does
not regress (keloid)
2-wound healing characterized by the formation of excessive
amounts of granulation tissue, which protrudes above the
level of the surrounding skin and blocks reepithelialization
