|Description||This chapter describes 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 lichen planusThis glossary term has not yet been described.|

(particularly in mucous lesions), but also in dermoscopy. White crossing streaks are a specific, as well as a constant finding for lichen planus, irrespectively of lesion’s duration or subtype.
