Histologically, they correspond to melanophages in the papillary dermis and reveal a final stage in the regression process of an LPLK (Watanabe et al., 2016). 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 LPLK can also show pinkish areas, an annular/granular pattern or a gray pseudonetworkA structureless pigment area interrupted by non-pigmented adnexal openings (Watanabe et al., 2016).
