Trichotillomania manifests as a compulsive desire to pull out own hair. The clinical presentation of trichotillomania is usually characteristic, with varying length hair distributed within areas of alopecia on otherwise normal scalp. In severe forms, tonsure pattern of baldness results, involving the entire scalp sparing the hair at the margins. Extensive tonsure pattern trichotillomania is rare and difficult to differentiate from other nonscarring alopecias on clinical grounds alone. Trichoscopy and histopathology of scalp play a corroborative role in definitive diagnosis. We hereby report two cases of extensive tonsure pattern trichotillomania, with special reference to their trichoscopic and histopathological features.
拔毛癖表现为一种拔自己头发的强迫性欲望。拔毛癖的临床表现通常具有特征性，在其他部位正常的头皮上，脱发区域内分布着长短不一的头发。在严重的情况下，会出现斑秃样秃发，累及整个头皮，边缘头发除外。广泛的斑秃样拔毛癖很少见，仅根据临床情况很难与其他非瘢痕性脱发相鉴别。头皮的毛发镜检查和组织病理学检查在明确诊断中起辅助作用。我们在此报告两例广泛的斑秃样拔毛癖病例，并特别提及它们的毛发镜和组织病理学特征。
