Dermatophyties et dermatophytes

Cutaneous diseases due to dermatophytes are common, usually superficial and not severe in most patients. Epidemiological data are in permanent evolution, especially for tinea capitis, in which causal agents have change a lot during the XX^th century. We describe classical presentations, the most frequent and other atypical forms, especially deep and extensive localizations in immuno-compromised patients. Laboratory testing allows the identification of causative agent, owing to improved sampling procedures. Within the last fifteen years, new topical and general therapeutic agents have been marketed, resulting in significantly improved treatment benefits.
