【 摘 要 】
Trichotillomania (TTM) is an impulse-control disorder, in which patients chronically pull hair from the scalp and/or other sites. We herein report a 8-year-old male patient who developed TTM in the classical tonsure pattern ("Friar Tuck" sign). The diagnosis was confirmed by trichoscopy, which showed decreased hair density, broken hairs with different shaft lengths, black dots, signs of hemorrhage, and an absence of exclamation mark hairs.
