This chapter reviews acquired changes in dermal connective tissue during normal ageing and in disease processes, including photodamage. Corticosteroids are a potent cause of dermal atrophy, which may also be congenital or induced by inflammatory disorders related to morphoea. Enzymatic degradation of elastic tissue results in localised or generalised skin laxity, which resembles genetic disorders such as pseudoxanthoma elasticum and cutis laxa. In contrast, some disorders are characterised by excessive deposition of collagen or elastic tissue. Fibrosis is associated with contracture, which causes deformity and restricted movement as in palmoplantar fibromatosis. Several chemical environmental triggers induce diffuse fibrosis resembling systemic sclerosis. Keloids represent an abnormal scarring response to trauma. Finally, dermal connective tissue components may be extruded via the epidermis in perforating disorders such as elastosis perforans serpiginosa.

After a review of the physiology in the formation and degradation of cutaneous elastic tissue, we describe the clinicopathologic disorders characterized by increased and decreased cutaneous elastic tissue. Cutaneous disorders characterized by increased and/or abnormal elastic tissue in the dermis include elastoma, also named nevus elasticus, dermatosis lenticularis disseminata, pseudoxanthoma elasticum, late-onset focal dermal elastosis, linear focal elastosis, elastoderma, elastofibroma dorsi, and elastosis perforans serpiginosa. In some of these conditions, the specific histopathologic diagnosis may be rendered with hematoxylin-eosin stain, whereas in other ones special elastic tissue stains are necessary to demonstrate the anomalies. Cutaneous disorders characterized by decreased dermal elastic tissue include nevus anelasticus, papular elastorrhexis, perifollicular elastolysis, anetoderma cutis laxa, postinflammatory elastolysis and cutis laxa, white fibrous papulosis of the neck, pseudoxanthoma elasticum–like papillary dermal elastolysis, and mid dermal elastolysis. In most of these conditions, the histopathologic anomalies are only seen with elastic tissue stains, and cutaneous biopsies of these processes stained with hematoxylin-eosin show appearance of normal skin. The diagnosis of some of these disorders characterized by increased or decreased elastic dermal tissue should be followed by general exploration of the patient to rule out associated severe systemic anomalies, and in some cases, a genetic counseling should be offered to the family.
