Videodermoscopy in the evaluation of hair and scalp disorders

Standard methods used to diagnose scalp and hair disorders vary in sensitivity, reproducibility and invasiveness. Recent data show that videodermoscopy can be used as a method which can improve our clinical and diagnostic accuracy in the evaluation of these disorders, since clinical diagnosis is not always suffi cient, and pathological fi ndings can sometimes be unspecific and therefore not always very helpful. Videodermoscopy has been used in the evaluation of several clinical diagnoses such as psriasis, seborrheic dermatitis, alopecia areata, androgenetic alopecia, chronic telogen effl uvium, trichotillomania, discoid lupus erythematosus, lichen planopilaris, and folliculitis decalvans. In literature reports, yellow dots as a dermscopic feature were present in 95% of alopecia areata cases but in only 5% of androgenetic alpecia. The presence of this feature allows us to differentiate alopecia areata from trichotillomania and telogen effl uvium. This fact allows us to have correct diagnosis without performing biopsy, which can be a very traumatic procedure in children. At the end, we can say that videodermoscopy is a very useful tool in clinical management and follow up of scalp and hair diseases, since it gives important information that can help us obtain an accurate diagnosis without performing scalp biopsy. However, it is necessary to perform prospective studies and get information on the power of dermoscopic features described to date.
