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.

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