title: Pseudoxanthoma-like late-onset focal dermal elastosis.
abstract: A 73-year-old woman presented with a 10-year history of asymptomatic coalescent flat pale yellow lesions forming a cobblestone pattern that resembled pseudoxanthoma elasticum over her neck, upper trunk and axillae. Skin biopsies from both the neck and axilla showed focal upper dermal elastosis with increase in structurally normal elastic fibres. There was no evidence of either pseudoxanthoma elasticum or solar elastosis in either biopsy. This under-recognized presentation has previously been identified as a distinct clinicopathological entity and termed late-onset focal dermal elastosis.
