Which staining method leaves hemosiderin unstained?

Mallory's Fuchsins is the correct answer because this staining method is primarily used to highlight proteins, especially in the contexts of liver and connective tissue pathology. When using Mallory's Fuchsins, structures such as collagen, elastin, and muscle fibers become well-stained, but hemosiderin, which is a storage form of iron and typically presents as golden-brown granules in tissue sections, remains unstained. This peculiarity is important for pathologists as it allows them to differentiate between various tissue components without interference from hemosiderin.

Other staining methods like Gomori's Aldehyde and Turnbull's blue focus on different aspects of tissue composition. Gomori's Aldehyde is mainly used to reveal reticular fibers and may not specifically highlight or affect hemosiderin. Turnbull's blue is explicitly used for iron deposits, resulting in hemosiderin appearing blue, indicating that it is not suitable for leaving hemosiderin unstained. The Modified Fouchet's technique, while aimed at detecting bile pigments, also does not influence hemosiderin staining the same way Mallory's Fuchsins does. Hence, Mallory's Fuchsins distinctly allows for the observation of other tissue structures without the interference of hemos
