3
Recent Thrombustwo colors are evident in the
thrombus
4
Recent Thrombus(Lines of Zahn) the pale line is
composed of platelets and fibrin, while the dark
red contains RBCs
5
Organizing Thrombusrecanalization and
inflammation
6
Organizing Thrombuswith time, the thrombus
induces inflammation and fibrosis
7
Organizing Thrombusrecanalization new
penetrating vessels are formed inside the
thrombus (arrow)
8
Normal Coronary Artery

Atherosclerosis with recanalization and
calcification (arrow)

Medial calcific sclerosis
16
Aortic Dissectionthere is an intimal tear within
the wall of the artery
17
Capillary Hemangiomathere is proliferation of
small sized vessels containing RBCs
18
Cavernous Hemangiomathere is proliferation of
medium sized vessels containing RBCs
19
Myocardial muscle fibres

Myocadial Infarctionnecrotic myocytes are
infiltrated by neutrophils

22
Lung Infarctionlung has dual circulations,
allowing blood to flow when one is obstructed.
The infarction is red.
23
Bowel infarctionthe bowel has red infarction
24
Early AtherosclerosisFatty streaks are seen
