			Features:

			**Described as running perpendicular to the surface<ref name=Ref_Derm499>{{Ref Derm\|499}}</ref> - this may not be apparent.

			</pre>

			===Micro===
			The sections show skin with a dermis with dense collagen fibres that run parallel to the skin surface without adnexal structures. The overlying dermal-epidermis interface lacks the typical undulation.
