Trichotillomania is a form of traction alopecia resulting from repetitive and compulsive hair pulling and plucking. Trichotillomania and patchy alopecia areata may have similar clinical and dermoscopic features in some cases. On trichoscopic examination, the presence of black dots, coiled or hook hair, shafts of varying lengths with fraying or split ends (trichoptilosis), and an absence of exclamation mark hairs and yellow dots are suggestive of trichotillomania.
拔毛癖是一种因反复强迫性拔毛而导致的牵引性脱发。在某些情况下，拔毛癖和斑秃可能具有相似的临床和皮肤镜特征。在皮肤镜检查中，出现黑点、卷曲或钩状毛发、长度不一且有磨损或分叉末端的发干（毛发纵裂症），以及没有感叹号样毛发和黄点，提示为拔毛癖。
