[Tinea capitis: new insights into an old disease].

Tinea capitis is a superficial dermatophytic infection of the scalp. This common dermatosis occurs predominantly in children. The clinical manifestation of the disease is heterogeneous, and vary widely depending on the pathogenic fungal agent. Direct mycological examination and cultures are mandatory for an accurate diagnosis and species identification. Treatment should be both local and systemic, and ideally is tailored to the dermatophytic species identified by the laboratory diagnostic work up. Secondary prophylaxis through supplementary measures is crucial to avoid epidemic outbreak and patient reinfection.
