Cardiovascular System
1. Acute myocardial infarction
HYALINE” = BENIGN HTN. 1) ONION SKIN
13. Arterial arteriosclerosis with mural thrombosis
“HYPERPLASTIC” = MALIGNANT HTN.
14.Arteriolosclerosis renis - hypertensive arteriopathy
HYALINE” = BENIGN HTN. “HYPERPLASTIC” = MALIGNANT HTN.
1) ONION SKIN 2) “FIBRINOID” NECR.
Explanation of Hyaline arteriolosclerosis
(Benign nephrosclerosis )
25.Trombosis acuta
Recent coronay thrombosis
32. Fibrinous pericarditis

30. Endocarditis polyposa
44. Polyarteritis nodosa (kidney) – Renal infarction
52. Mesaortitis luetica Mainly
thoracic and plasma cells predominate
58.granulation tissue scar
58.Granulation tissue
Luetic aneurysm – comp of tertiary sy. Treponemas
in vasa vasorum induce plasma cell vasculitis that
will obliterate these vessels – Ischaemia of aortic
media, fibrous repacement of medial smooth
muscle and loss of elasticity.
the media is highly vascularized and hyperemic,
and there are heavy collections of deeply
basophilic cells
GT- Active fibrosis and ch inflamatory cells.
Angiogenesis- growth of small blood vessels in
area of tissue Damage.
Venous thrombi – lack proiminent lines,
formed by stasis and pooling.
Repeated microinfarts- (angina pectoris) –
reparation by gr tissue, scarring. Disperse scars ,
small whitish foci in myocardium.
59. Organisation of a thrombus- 56. Myofibrosis dispersa cordis

Cardiovascular System
Arterial thrombi- alternating layers of fibrin and RBC
– lines of Zahn – extend, propagate.
