What is the diagnosis?
M1 or classical proinflammatory macrophages
M2 or anti-inflammatory macrophages
Cholesterol clefts in the necrotic area
Correct! The correct answer is "M2 or anti-inflammatory macrophages"
 
M2 macrophages are signal-rich, confluent, punctate spots exceeding background intensity & attenuating OCT light with a bright appearance due to the higher density of light-scattering mitochondria. 
Good try! The correct answer is "M2 or anti-inflammatory macrophages"
 
M2 macrophages are signal-rich, confluent, punctate spots exceeding background intensity & attenuating OCT light with a bright appearance due to the higher density of light-scattering mitochondria.
