“…The most common reports are of granuloma annulare [ 74 , 75 , 76 ] and other granulomatous processes, including necrobiosis lipoidica [ 77 , 78 ], sarcoid [ 79 ], and elimination of suture material [ 80 ]. Other reports include perforating pseudoxanthoma elasticum [ 81 , 82 , 83 ], pilomatrixoma [ 84 , 85 , 86 ], sialolithiasis [ 87 , 88 ], lichen nitidus [ 89 , 90 ], and osteoma cutis [ 91 ]. Unusual reports of perforating cryocrystalglobulinemia in the context of multiple myeloma [ 92 ] and perforating ochronosis [ 93 ] again underscore the importance of a categorical approach over rigid adherence to previously published lists.…”

Perforating dermatoses are dermatologic disorders with transepidermal elimination (TE) of dermal substances. While TE is typically associated with collagen and elastin, it can also occur as a secondary event in other processes, and it is important to keep a broad differential. We present a case of perforating tophaceous gout, which underscores the need for a thoughtful approach to perforating disorders. An updated review of recent literature is also presented.

Acquired Disorders of Dermal Connective Tissue

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.
