title: Treatment of facial scarring and ulceration resulting from acne excoriée with 585-nm pulsed dye laser irradiation and cognitive psychotherapy.
abstract: BACKGROUND
  Self-inflicted skin ulcers and scars are often observed in patients with compulsive skin picking. The term "neurotic excoriation" has been used to describe this condition and may or may not coexist with other true skin pathologies, such as acne. The condition poses a diagnostic and treatment challenge because patients often also have an undiagnosed underlying psychologic disorder.
  
  
  METHODS
  Two patients with numerous linear and stellate facial ulcers and hypertrophic and erythematous scars were diagnosed with acne excoriée in the setting of an obsessive-compulsive disorder linked to emotional stress and anxiety. The scars were treated with a 585-nm flashlamp-pumped pulsed dye laser using a 7-mm spot size, 1.5-msec pulse duration, and fluence range of 4.5 to 6.0 J/cm(2). The patients received concomitant cognitive psychodynamic therapy to halt the cycle of impulse-driven skin picking and ulcer/scar formation. Marked clinical improvement of the scars and successful treatment of the acne excoriée were achieved with this combination approach. Relapses occurred when psychodynamic intervention was interrupted.
  
  
  CONCLUSIONS
  The 585-nm flashlamp-pumped pulsed dye laser improves the appearance of hypertrophic erythematous facial scars and ulcers in patients with severe acne excoriée. Proper diagnosis of underlying impulse-control disorders and ongoing psychodynamic therapy is necessary to maintain improvement.
