Tinea Capitis in Children and Trichoscopic Criteria.

Tinea capitis is the most common pediatric superficial dermatophyte infection. The causative species vary, as for instance, Microsporum canis predominates in Europe, while Trichophyton tonsurans predominates in North America. Tinea capitis does not respond well to topical therapy alone, thus oral therapy is requisite. The drug of choice is griseofulvin; however in some countries, it is no longer available. Fungal culture should be requested in the persistent, scalp lesion and trichoscopy can put forward a speedy diagnosis by its characteristic findings. Scalp dermoscopy or "trichoscopy" represents a valuable, noninvasive technique for the evaluation of patients with hair loss due to tenia capitis. It is simple, quick, and easy to perform.
