Figure 3 Sclerodermoid GVHD after allogeneic hematopoietic stem cell transplantation. (A) Morpheaform induration
on the back with overlapping atrophic hypopigmented plaques of lichen sclerosus. Note the superficial ulceration and
erosions with hemorrhagic crusting. (B) Multiple well-demarcated ulcers with fibrinous bases overlying shiny hypopigmented
plaques with follicular plugging, admixed with hyperpigmentation and superimposed on background of
diffuse sclerodermoid induration. (C) Classic lichen sclerosus lesions demonstrating hypopigmentation, ‘cigarette
