Gomori Burtner demonstration highlights which pigment?

• A. Melanin
• B. Elastic fibers
• C. Reticulin
• D. Bacteria

Answer: (A)

The Gomori Burtner demonstration is used to reveal melanin pigment in tissue. Melanin is the dark brown to black pigment produced by melanocytes and stored in cells of the skin, hair, and some internal sites. This demonstration highlights those pigment granules, helping distinguish true melanin from other pigments or artifacts. Elastic fibers and reticulin are identified with separate staining methods (elastic with specialized elastin stains, reticulin with silver-based reticulin stains), and bacteria are detected with microbiologic stains, not this pigment-focused demonstration.
