Hematoxylin and eosin-stained histological sections of our radicular cyst studied by conventional (white light) and polarized light microscopies. (A, B, C and D) Low-, medium-, and high-power microphotographs exhibiting a radicular cyst lined by stratified squamous epithelium. A lot of cholesterol clefts and a moderate lymphoplasma cell infiltrate were discovered in the fibrous cystic wall. In addition, depositions of small brown particles were found in the cystic lumen and in some areas of the fibrous cystic walls. (E and F) By polarized light microscopy, the brown particles showed birefringence and the collagen bundles also exhibited thin band birefringence with marked cross striations (Hematoxylin and eosin stain; original magnification; A, 4×; B, 10×; C, D, E, and F, 20×).
