case_images: A 72-year-old, Caucasian, phototype II female presented with scalp hair loss, with progressive frontotemporal hairline recession and diffuse alopecia of eyebrows and eyelashes of one year's duration (Figure 1).

case_images: Dermoscopic features were a pseudo-network pattern and areas with gray dots arranged in circles, without telangiectasias or other vascular images (Figure 3).
case_images: A - Slightly atrophic epidermis with effacement of rete
  ridges. In the dermis, there is a lichenoid reaction and melanophages
  (Hematoxylin & eosin, X20). B - Foci of vacuolar
  changes of the dermo-epidermal interface and abundant melanophages
  deeper in dermis than in postinflammatory pigmentation (Hematoxylin
  & eosin, x20)
