Below are dermoscopic features commonly associated with the diagnosis “Dermoscopic features of the face”.[1] The example images have been approved by a panel of experts as representative of each given feature.

For a more in-depth discussion of associated features, please see the Dermoscopedia page for “Face”.

Pseudonetwork pattern

The anatomy of the rete ridge pattern of the face differs from that of non-facial skin, and is usually flatter. Accordingly, the pigment network is usually absent in these locations and is replaced by a pseudonetwork pattern. The "holes" in the pigmented epidermis correspond histologically to adnexal openings, such as sebaceous glands, hair follicles or sweat glands.[2]
