Acute erosion, with early organization, Movat pentachrome. (a) Low magnification of a cross section of the left anterior descending coronary artery, at the branch point of the first diagonal. The intimal plaque is smooth muscle cell rich without atheromatous core formation. (b) There is a nonocclusive luminal thrombus, with a single strand of fibrin incorporated in the smooth muscle cell, proteoglycan rich cap. (c) Higher magnification of (b), demonstrating the acute nonocclusive thrombus on the left, and the fibrin incorporated within the cap on the right.
