case_images: Skin punch biopsies before ((a) at 4x magnification; (b) at 10x magnification) and after ECP ((c) at 4x magnification; (d) at 10x magnification). Despite clinical improvement, interval changes in histology were not dramatic. Fibrocollagenous thickening of dermis was seen in both biopsies. In addition, dermal perivascular plasmacytic infiltrates were minimal in both biopsies.

case_images: Skin punch biopsy performed at presentation was noteworthy for increased cellularity, thick and thin collagen fibers, and elastic preservation (Figures 1(a) and 1(b)). Interestingly, despite significant clinical improvement, biopsies after completion of ECP treatment did not reveal significant changes compared to biopsies prior to ECP (Figures 1(c) and 1(d)).
