Description This chapter covers 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. of discoid lupus erythematosusis a chronic skin condition of sores with inflammation and scarring favouring the face, ears, and scalp and at times on other body areas. These lesions develop as a red, inflamed patch with a scaling and crusty appearance. The centre areas may appear lighter in colour with a rim darker than the normal skin. of the scalpThis glossary term has not yet been described.

Characteristic trichoscopic findings of discoid lupus erythematosus include large yellow dotsDots are small, round structures of less than 0.1 mm in diameter that have a red color when corresponding to blood vessels; however, when due to melanin, their color ranges from black, brown, to blue-gray depending on the depth and concentration of the melanin in the skin (Tyndall effect)., red dots and large yellow dots with radial, thin arborizing vesselsanalytic term is branched vessels; Bright red sharply in focus large or thick diameter vessels dividing into smaller vessels; BCC emerging from the dotSee [[Glossary:Dots|Dots]] (also known as “red spider in yellow dot”). Other typical trichoscopic features of the diseaseThis glossary term has not yet been described. are thick arborizing vessels, scattered dark-brown discoloration and blue-grey dots arranged in a “speckled” pattern (2).

The active (early) discoid lupus erythematosus is characterized by presence of thick arborizing vessels, large yellow dots, fine interfollicular scaling, red and blue-grey dots and brown discoloration (4, 5) (3).In inactive (end-stage) lesions mainly white and milky-red areas with lack of follicular openings, arborizing vessels and yellow dots containing thin spider vesselsThis glossary term has not yet been described. are observed (4).
