A 19-year-old well-nourished girl presented with a 4-year history of hair loss. On past history, she has been treated with narcolepsy for four years. She had a low self-esteem and was distressed for her obesity. On her frontal and left temporal area, several ill-defined patches of hair loss were seen. And the hairs in that area, they are short, irregular, broken and distorted. She denied the fact she pulled out hairs, but in the morning, there were several hairs on her bedside. Histopathologic exam shows an increase in catagen hairs, pigmentary defects and casts, and trichomalacia. We herein report a case of trichotillomania occurring on the patient with narcolepsy. It is uncertain that the narcolepsy affects the development of trichotillomania, but her depressed mood may affect the development of narcolepsy as well as the development of trichotillomania.
