ABSTRACT

Alopecia areata (aa) is the most frequent cause of hair loss in childhood, representing 20% of cases. The pathophysiology focuses on an autoimmune origin where the hair follicle loses its “immunological privilege” possibly due to a previous infectious process. The diagnosis is clinical aided by dermoscopy, especially to differentiate it from trichotillomania and tinea capitis, also frequent in this age group. Treatment, when it comes to the most common clinical form that is self-limiting plaques, is encouraging with the use of topical corticosteroids; however, when it is the total form, it is usually long treatment and with recurrences. We present a 8-year-old boy with total alopecia areata and who evolved satisfactorily to narrowband UVB phototherapy in combination with other topical treatments.
