|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 vasculitisThis glossary term has not yet been described.|

Scarce evidence exists on the dermoscopic pattern of vasculitides. Henoch-Schonlein purpura has been shown to dermoscopically reveal irregularly shaped red patches with blurred borders. Reported findings of urticarial vasculitis are described above.In granuloma faciale, the specific dermoscopic features are dilated follicular openings, perifollicular whitish halo, follicular keratotic plugs and linear branching vesselsThis glossary term has not yet been described.. Clinically, granuloma faciale has to be differentiated from sarcoidosisThis glossary term has not yet been described., 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., lupus vulgarisThis glossary term has not yet been described., lymphomaThis glossary term has not yet been described. and basal cell carcinomais the most common skin cancer, and one of the most common cancers in the United States. While BCC has a very low metastatic risk, this tumor can cause significant disfigurement by invading surrounding tissues. The mentioned dermoscopic patternsThis glossary term has not yet been described. simplify clinical differential diagnosisis the identification of the nature and cause of a certain phenomenon. Diagnosis is used in many different disciplines with variations in the use of logic, analytics, and experience to determine "cause and effect". In systems engineering and computer science, it is typically used to determine the causes of symptoms, mitigations, and solutions. But the distinction from discoid lupus erythematosus, which exhibits similar findings, remains challenging.
