    Abstract:
    Tinea capitis is a common fungal infection of the scalp, primarily affecting children, and caused by fungi like Trichophyton and Microsporum. Its pathogenesis is influenced by both host-specific and environmental factors, resulting in various clinical presentations including hair loss and scaling of the scalp. We present the case of an eight-year-old male with tinea capitis, characterized by itching and hair loss in the occipital area. Examination revealed characteristic findings on trichoscopy, and direct examination of hair confirmed parasitization. Treatment with terbinafine was initiated, leading to the resolution of symptoms. Epidemiological variations in the etiology of tinea capitis exist globally, with Trichophyton predominating in some regions and Microsporum in others. Trichoscopy is a valuable diagnostic tool for differentiating fungal infections, guiding treatment decisions. Despite the efficiency of direct skin and hair examination, the common occurrence of tinea and the lack of mycological centers in many clinics pose challenges. To address this, we propose integrating trichoscopy and epidemiological and clinical data for a quick in-office decision tool.
