TRANSCRIPT
ACUTE and CHRONIC INFLAMMATION
Vascular congestion
Acute inflammation with edema
Leukocytic margination
Acute pneumonia
Acute esophagitis
6Acute inflammation in myocardium
the liquefactive necrosis in a cerebral infarction
Morphologic patterns of inflammation
Serous inflammation
fibrinous inflammation
yellow-tan clouding of the meninges: acute meningitis
yellow-tan exudate obscures the sulci
neutrophilic exudate is seen involving the meninges
yellow to tan exudate and hyperemia, including the periappendiceal fat
tan-yellow exudate
gastric ulcer
