The dark purplish lining that looks irregular shows the disruption of the internal elastic lamina.]]Giant cell arteritis, or temporal arteritis (when it affects the temporal artery) is a granulomatous inflammation that affects large arteries. Characteristic for the disease is that only certain parts of the affected artery show the histological signs of inflammation. If a preparation was taken from one of these parts could a false negative diagnosis be made. Optimally should a longitudinal section of the artery be examined, or multiple cross-sections (which could be why we have three sections here).
