A combined elastic tissue-Masson technique is presented which stains elastic fibers of all sizes, nuclei and connective tissue. The modified elastic tissue stain consists of hematoxylin, ferric chloride and Verhoeff's iodine; nuclei and elastic fibers are stained blue-black in six minutes without differentiation. By contrast, cytoplasmic elements are stained red, (Biebrich scarlet-acid fuchsin) and collagen is stained green (light green) or blue (aniline blue). The entire staining procedure takes approximately one hour.
