Tiny/microscopic stones in gallbladder
These small stones, less than 1 mm in size, are embedded in the gallbladder mucosa. They are composed primarily of cholesterol crystals, which acquire a bluish color when mixed with a protein or other mucus-derived substance that is stained with hematoxylin. The stones are mixed, as they have a bilirubin layer. The photo below shows the same stones polarized, where the birefringence of the cholesterol crystals can be observed.
