Arteritis, temporal, (giant cell or granulomatous arteritis):
Chapter: 10
Focal, chronic, granulomatous inflammation of the temporal arteries. It can occasionally involve other cranial arteries, the aorta and its branches. Grossly, the affected artery is cord like with nodular thickening and narrowing of the lumen. Microscopically, there is granulomatous inflammation of the media and intima with varying admixtures of chronic and acute inflammatory cells, histocytes and giant cells. A thrombus may be present. It is most common in older adults.
