Dermatophytosis: the management of fungal infections.

Dermatophytosis is an infection of the hair, skin, or nails caused by a dermatophyte, which is most commonly of the Trichophyton genus and less commonly of the Microsporum or Epidermophyton genera. Tinea capitis, tinea pedis, and onychomycosis are common dermatologic diseases that may result from such an infection. The treatment of fungal infections caused by a dermatophyte has been successful when treated with oral or topical antifungal agents. Terbinafine, itraconazole, and fluconazole are oral antimycotics that are effective in the treatment of superficial mycoses, although, depending on the severity of the infection, a topical antifungal may be sufficient.
