An 18-year-old woman presented with a one-year history of erythematous to slightly violaceous indurated papules and plaques on the face (Figure 1), earlobes, neck, upper arms, chest, and upper back. The lesions did not have scale. The patient reported significant photosensitivity and worsening of lesions after sun exposure, but was otherwise healthy. Serology for antinuclear antibody was negative. Basic laboratory workup including complete blood count, chemistry panel, and urinalysis was normal.
