Microscopic findings (higher magnification). (a) Hematoxylin-eosin stain. (b) Alcian blue stain. (c) Immunoreactivity to CD 68. (d) Immunoreactivity to SMC α-actin. Fibrous collagenous plaque is adjacent to the lesion where polymorphic SMCs proliferate with rich proteoglycan at the background. (From J Invasive Cardiol 23: E86–E91, 2011 with permission).
