Routine hematoxylin-eosin staining revealed a normal-appearing epidermis with increased elastic fibers throughout the dermis (Fig 2, A). There was an increase in intact and fragmented elastic fibers in the papillary dermis with some aggregation of elastic fibers seen with a Verhoeff-Van Gieson stain (Fig 2, B and C). von Kossa staining was negative for calcified elastic fibers, confirming the diagnosis of linear focal elastosis.
