Histologic Changes

This artery is undergoing remodeling. Some smooth muscle of the media remains (arrow), but most has been replaced by granulation tissue with myxoid stroma and inflammatory cells. Inflammatory cells consist of lymphoid cells, as well as mast cells, eosinophils, and PMNs.

A mast cell (upper arrow) and a group of cells with lobated nuclei, representing PMNs and eosinophils (lower arrow) is seen at higher magnification.
