title: Diffuse alopecia in an adolescent female: tinea capitis.
abstract: "Black dot" tinea capitis is a common cause of alopecia in young patients. It is most commonly caused by a dermatophyte infection with Trichophyton tonsurans. This entity can be easily distinguished from alopecia areata with the use of hair/scalp dermoscopy. The use of oral terbinafine is effective in resolving the infection.
