From: Calcification of the internal elastic lamina of coronary arteries
A 44-year-old woman with AIDS (Table 1). Example of calcification of the internal elastic lamina in a coronary artery with fibromuscular intimal hyperplasia: (a, b) H&E stain demonstrating linear basophilic staining between intima (I) and media (M) ((a) × 40, (b) × 100); (c, d) trichrome/elastic tissue stain confirming that the linear lesion is at the internal elastic lamina, which shows breaks associated with adjacent medial fibrosis (arrows) ((c) × 40, (d) × 100); (e) von Kossa stain; and (f) Alizarin red stain confirming the presence of calcium ((a, f) × 40).
