Temporal Artery Biopsies
are occasionally taken of the temporal artery in cases for which temporal
arteritis is suspected. These biopsies need to be carefully and thoroughly
examined, at multiple levels, for focal disease. The average biopsy is about 12
mm long. Cut it into four pieces, each about 3 mm long, and have the laboratory
embed each piece on end. We like to get four sets of step sections through the
block, each set containing three hematoxylin and eosin stained sections, one
elastin stained section (Verhoeff’s/van Gieson’s), and one unstained section.
Thus, one temporal artery biopsy pro-duces at least 16 slides to examine.
