Case study: delicate skin cutting: management beyond the skin and implications of superficial habitual...

A 16-year-old girl accompanied by her mother was noted to have several thin, well healed brown lines on the distal third of her left flexural forearm (Figure). She admits to having recently made these marks by skin cutting. She feels depressed and at times feels life "is not worth living." She denies alcohol or substance abuse or true suicidal ideation, plan, or intent. Her mother describes her as previously well adjusted and a good student who has become erratic and moody in the past 6 months, with worsening school performance. Her father had a history of depression and alcoholism and died 3 years ago. She is undergoing psychotherapy and pharmacotherapy with sertraline with good results. She has not cut her skin in 3 months. Her mood and behavior have improved.
