Vidéomicroscopie au cours de la pelade

Videomicroscopy allows a detailed semiological description of damage to the scalp. In the majority of patients with alopecia areata, the yellowish ring was centred around the ostium. A knowledge of the appearance of this finding is helpful in diagnosing diffuse forms of alopecia areata or forms likely to be confused with pseudo alopecia areata. It would perhaps be of value to investigate for a correlation between the semiological appearances noted in our study and the progression and prognosis of alopecia areata.
