|Description||This chapter covers the histopathological correlation of the 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. term pseudonetworkA structureless pigment area interrupted by non-pigmented adnexal openings|

The "holes" in the pigmented epidermis correspond histologically to adnexal openings, such as sebaceous glands, hair follicles or sweat glands.

Histologically, adnexal openings are responsible for the "holes" in the pigment reticulation:
