Trichotillomania Associated With The Friar Tuck Sign And Nail-Biting

The document discussed trichotillomania, a form of traction alopecia caused by compulsive hair pulling, which could resemble other types of hair loss such as alopecia areata and androgenetic alopecia. It emphasized the importance of distinguishing trichotillomania from other alopecias due to differing treatments. The study presented three cases exhibiting the "Friar Tuck sign," a tonsure pattern of hair loss, and onychophagia (nail-biting) as identifying features of this condition.
