Fig. 2 A, Organizing thrombus within pit of an atheromatous plaque (Masson trichrome stain, original magnification × 45). B, High-power view of organizing thrombus in A shows irregular thin-walled anastomosing vessels. Vessel outlines resemble those of the angiomatoid structures observed in many plaques (Verhoeff-van Gieson stain, original magnification × 450).
