title: Cutaneous lupus erythematosus limited to the site of a laceration.
abstract: BACKGROUND
  Cutaneous lupus erythematosus is known to occur at sites of trauma or inflammation of the skin, including sites of tattoo, frostbite, herpes zoster scar, burn scar, and implantation by windshield glass.
  
  
  OBJECTIVE
  We report a 32-year-old white man who developed cutaneous lupus erythematosus at the site of a laceration. The diagnosis was confirmed by histologic and immunofluorescence examination. The patient responded to intralesional corticosteroid and hydroxychloroquine therapy.
  
  
  CONCLUSIONS
  Lupus erythematosus may be induced by trauma.
