A 9-year-old black girl presented with papules and nodules in a linear distribution on her right inner arm, right axilla, and right chest ( Fig. 1). The lesions were hyperpigmented, indurated, and had been present for 3 years. She was otherwise healthy. A biopsy of one of the lesions revealed a sparse superficial and deep perivascular infiltrate of lymphocytes, compactly arranged collagen bundles in the upper part of the dermis, and abundant mucin throughout the reticular dermis, which was consistent with morphea with dermal mucinosis ( Fig. 2). Biopsy of another lesion revealed classic histologic features of morphea: thickened bundles of collagen crowded in the reticular dermis aligned parallel to the skin surface.
