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 folliculitis decalvans

Tufted hairs (multiple hairs emerging from a single dilated follicular opening) are the most common and characteristic trichoscopic finding of folliculitis decalvans (2) (6). Other trichoscopic features include perifollicular hyperplasia arranged in a starburst patternThis pattern consists of peripheral globules, pseudopods or streaks (or a combination of them), located around the entire perimeter of the lesion, yellowish tubular scaling (with a collar-like widening at the distal end), crusting, and follicular pustules (7). In the late, inactive diseaseThis glossary term has not yet been described. white and milky-red areas with lack of follicular openings are observed (4).
