Abstract
Background: Alopecia is a common scalp disorder. Now a days trichoscopy is emerging as an important tool in diagnosis of various scalp alopecias. Objective: To observe trichoscopic findings of various cicatricial and non cicatricial scalp alopecias. Methods: A hospital based observational study was performed in one hundred consecutive patients with alopecia. Detailed history, clinical examination, investigation and trichoscopy was performed using a non-polarized trichoscope. Result: Out of one hundred patients majority were Alopecia areata (42%) followed by Androgenetic alopecia (35%), Lupus erythematosus(4%),Tinea capitis(7%), Telogen effluvium(5%) and Trichotillomania(1%). In Alopecia areata yellow dots were the most common finding followed by black dots and exclamation marks. In AGA yellow dots, thin and vellus hair were seen. In Telogen effluvium most common finding was thining of hair. In lichen plano pilaris perifollicular inflammation and perifollicular silver white scaling was seen. In tinea capitis comma hair was most common finding followed by cadaverised hair. In trichotillomania broken hair and cadaverized hair were seen. Limitations: the small number of patients in various types of alopecia was a limiting factor. Conclusions: Trichoscopy is a very simple, cost effective and non invasive diagnostic tool in hair and scalp disorders, help in differentiating some of the difficult cases of alopecia.
