Are Verhoeff and aldehyde fuchsin elastic stains?

• A. True
• B. False
• C. Only Verhoeff
• D. Only Aldehyde fuchsin

Answer: (A)

Elastic fibers are best seen with stains that selectively bind elastin. Verhoeff’s elastic stain and aldehyde fuchsin are two classic methods that specifically highlight elastic fibers, staining them dark (often black or purple-black) while the surrounding tissue takes a contrasting color. Verhoeff’s method uses a mordant system with iron hematoxylin to bind elastin, whereas aldehyde fuchsin uses aldehyde fuchsin chemistry to stain elastin directly. Because both stains are designed to reveal elastic fibers, the statement is true.
