Description This chapter covers 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 superficialThis glossary term has not yet been described. spreadingThis glossary term has not yet been described. melanomaThis glossary term has not yet been described., nodular melanomaThis glossary term has not yet been described., lentigo malignaThis glossary term has not yet been described., etc.
