A 48-year-old Chinese man presented with a 2-day history of an asymptomatic linear lesion on his neck that he had noted incidentally. He had no history of trauma or previous surgery. He had unquantified exposure to UV light during the course of his work as a commercial pilot. He had no significant involvement in outdoor activities, and he was otherwise well. His family history was unremarkable.
Physical examination revealed a 5-cm, curvilinear, yellow plaque over the anterior aspect of the neck (Figure 1). A punch biopsy specimen was obtained and sent for routine histopathologic examination (Figure 2) and elastin staining (Figure 3).
