Over a 10-month period, a 39-year-old woman developed asymptomatic, multiple, firm plaques on her trunk. The individual lesions were not well defined. They were associated with accentuated follicular orifices (peau d’orange) and patchy hypo- and hyperpigmentation (Figure 1). Skin biopsy showed an expanded dermis with lymphocytic inflammation as well as marked dermal sclerosis that was most evident within the deep dermis and subcutis (Figure 2).
