Histologic examination of the biopsy specimen revealed a perivascular chronic inflammatory infiltrate in the superficial dermis. The dermis was edematous, and the collagen bands in the middle dermis appeared separated (Figure 2). Elastic van Gieson staining revealed fragmented, long and short, haphazardly arranged elastic fibers in the middle and lower dermis. There was a mixture of thick and thin and clumped elastic fibers (Figure 3).
