Contributed by Misha Rosenbach, MD

A 40-year-old female patient presents for evaluation of a discolored lesion on her outer shoulder. She is otherwise healthy and denies a history of blistering sunburns, tanning, or personal or family history of skin cancer or dysplastic nevi.

  • The lesion is asymptomatic, but cosmetically bothersome.
  • It has been present for months.
  • On exam the patient has a slightly pink-brown, hyperpigmented macule, which puckers inwards and dimples when gentle pressure is applied to the sides of the lesion.
