Extensive tonsure pattern trichotillomania-trichoscopy and histopathology aid to the diagnosis.
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.
