Name Christalline structures schematics.jpg
Label Cristalline structuresChristalline structures, are white shiny linear streaks that are seen under polarized dermoscopy, but not under nonpolarized dermoscopy. The white streaks are oriented parallel, and sometimes also orthogonal (perpendicular) to each other. Chrysalis structures can be seen in scars, dermatofibromas, basal cell carcinomas, and also in melanomas and Spitz nevi. These structures correlate histopathologically with altered collagen in the dermis (fibrosis). The birefringent properties of collagen bundles causes rapid randomization of polarized light and this is, why collagen appears bright white and more conspicuous under polarized dermoscopy. schematic
