Atherosclerotic Plaque (Medium Power)

Atherosclerotic Plaque (Medium Power) •Field shows atheromatous plaque in intima with no other layers of the arterial wall visible. •The more deeply pinker staining right upper portion of the field is the sclerotic fibrous cap (black asterisk). The lighter stain elsewhere is due to deposition of neutral fats which are washed out by the tissue processing for slide preparation. •Note the slit like clear spaces (black arrow) which were occupied by washed out cholesterol esters crystals before processing. •The fine blue stipples throughout are calcific spherules.
