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.

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.

Dermoscopic criterias differ depending on the stage of progression of discoid lupus erythematosus. In early lesions, perifollicular whitish halo, follicular plugging and white scales are the predominant features, while in longer-standing lesions telangiectatic vesselsThis glossary term has not yet been described., pigmentation structuresThis glossary term has not yet been described. and whitish structureless areas prevail.[1] This distinct dermoscopic pattern is useful for discriminating discoid lupus erythematosus from lupus pernio (cutaneous sarcoidosisThis glossary term has not yet been described.) and lupus vulgarisThis glossary term has not yet been described. (cutaneous tuberculosis). The latter diseases lack the predominant follicular abnormalities of discoid lupus erythematosus, and display a characteristic pattern consisting of orange-yellowish areas/globules and branching arborizing vesselsanalytic term is branched vessels; Bright red sharply in focus large or thick diameter vessels dividing into smaller vessels; BCC.[2]
