Fibroelastolytic Patterns of Intrinsic Skin Aging: Pseudoxanthoma Elasticum-Like Papillary Dermal Elastolysis and White Fibrous Papulosis of the Neck

Abstract

Pseudoxanthoma elasticum-like papillary dermal elastolysis is characterized by multiple whitish-yellow papules on the neck and supraclavicular regions of elderly persons. The papules resembles those in pseudoxanthoma elasticum. There is also an histological loss or decrease of the number in elastic fibers in the papillary dermis. There is no family history of such skin lesions and lack of cardiovascular or ocular abnormalities. White fibrous papulosis of the neck is characterized by several whitish to yellowish, tiny, firm papules located on the posterior or lateral sides of the neck in the elderly. We herein report a case of pseudoxanthoma elasticum-like papillary dermal elastolysis and another typical case of white fibrous papulosis of the neck. According to the literature, both diseases are best viewed as two fibroelastolytic patterns of intrinsic skin aging.
