Figure 3: (a and b) Thin epidermis with flat rete ridges and dense collagen bundles; (c) orange-red birefringence of old collagen fibers (original: ×400, ×200, ×100); (d) pin hole cutting the epidermis (arrow) with dermal infiltrate. (e) The recent collagen bundles laid down in lattice pattern. (f) A green birefringence fibers of recent fibers (arrow) dissecting the old red-orange ones (original: ×100, ×100, ×200). (g, h and i) Different collagen deposition with more mature yellow ones (original: ×100, ×100, ×100)
