Focal Dermal Elastosis: A Proposed Update to the Nomenclature.

Late-onset focal dermal elastosis is a clinical mimic of pseudoxanthoma elasticum that lacks associations with systemic disease. Although initial reports asserted that the disorder occurs only in the elderly, a growing body of case reports document cases in patients as young as 39 years. We present a case of a 59-year-old woman with this disorder. To reflect the broad age range of patients affected by this disorder, we propose the term "focal dermal elastosis."
