case_images: III skin. In the glabellar region, there was a solitary 7 cmx5 cm brown-purple, shiny, bossellated, annular, firm plaque with large overlying telangiectasias (Figure 1(a)). The ulcer healed and the lesion continues to flatten and lighten gradually but is still present (Figure 1(b)).
case_images: (a) A diffuse dermal infiltrate extends into the deep dermis, occasionally accompanying
  adnexal structures. A grenz zone is present. Note the superficial dilated lymphatics
  (10x magnification, H&E stain). (b) Higher magnification reveals a mixed population
  of plasma cells, neutrophils, eosinophils, lymphocytes, and histiocytes. Most vessels
  are dilated and are lined by plump endothelial cells (200x magnification, H&E
  stain).
