Fig. 17. Actinic (Solar) Elastosis—A. With standard hematoxylin-eosin staining, the areas of sun-damaged collagen stain present a somewhat vermiform appearance and stain more basophilic than the undamaged dermal collagen (hematoxylin and eosin stain). B. The Verhoff-VonGiesen elastic stain stains the damaged collagen like elastic tissue (Verhoff-VonGiesen stain). (Photos courtesy of William Morris, M.D.)
