The hematoxylin-eosin–stained biopsy specimen showed a normal epidermis, with a dense lymphohistiocytic infiltrate immediately below the epidermis in a bandlike arrangement, and around the blood vessels. The latter showed some degree of dilatation and endothelial swelling, with sparse extravasated red blood cells. Hemosiderin deposits were evident with Perls stain (Figure 3).
