Description This chapter describes the histopathological correlation of the dermoscopyThe examination of [skin lesions] with a 'dermatoscope'. This traditionally consists of a magnifier (typically x10), a non-polarised light source, a transparent plate and a liquid medium between the instrument and the skin, and allows inspection of skin lesions unobstructed by skin surface reflections. Modern dermatoscopes dispense with the use of liquid medium and instead use polarised light to cancel out skin surface reflections. term shiny white areasThis glossary term has not yet been described.

  • Shiny white streaksWhite lines that appear parallel and perpendicular to each other on polarized dermoscopy
  • Shiny white blotches and strandsWhite structures in the form of circles, oval structures, or large structureless areas that are bright-white longer and less well defined lines oriented parallel or distributed haphazardly, or forming blotches (shiny white clods). Seen only under polarized dermoscopy.
  • RosettesFour bright white dots or clods arranged together as a square (or a four leaf clover)
  • Shiny white areasThis glossary term has not yet been described.

Christalline structuresThis glossary term has not yet been described., are white shiny linear streakslines radial (always at periphery) streaks Reed nevus melanoma recurrent nevus that are seen under polarized dermoscopy, but not under nonpolarized dermoscopy. The white streaks are oriented parallel, and sometimes also orthogonal (perpendicular) to each otherThis glossary term has not yet been described.. Chrysalis structuresolt term for Chrysalis / Cristalline Structures can be seen in scars, dermatofibromas, basal cell carcinomas, and also in melanomas and Spitz neviThis glossary term has not yet been described.. These structures correlate histopathologically with altered collagen in the dermis (fibrosis). The birefringent properties of collagen bundles causes rapid randomization of polarized lightThis glossary term has not yet been described. and this is, why collagen appears bright white and more conspicuous under polarized dermoscopy.
