title: [Tropical and travel-related dermatomycoses: Part 1: Dermatophytoses].
abstract: Today, tropical and travel-related dermatomycoses must be increasingly anticipated to present in dermatological offices and clinics. Skin infections due to dermatophytes or other fungi may occur after a journey in countries with a high prevalence for the respective causative fungal pathogen, e.g., tinea corporis due to Trichophyton soudanense. Otherwise, more frequently, single infections and even localized outbreaks due to "exotic" or "imported" pathogens of dermatophytoses occur. These epidemics are observed in childcare facilities in Germany and in other European countries. Source of infection are immigrants from Africa and sometimes from Asian countries. Furthermore, African children, and sometimes also adults, are often only asymptomatic carriers of such anthropophilic dermatophytes. Outbreaks of dermatophyte infections with one and more affected children and also adult staff and teachers due to Trichophyton violaceum or Microsporum audouinii in kindergartens and schools are not a rarity these days. Further tropical and travel-associated dermatophytes are Trichophyton tonsurans, Trichophyton schoenleinii, and Trichophyton concentricum. Tinea capitis should be treated in a species-specific manner. Griseofulvin is the treatment of choice for infections due to Microsporum species. In contrast, tinea capitis due to Trichophyton species has to be treated by terbinafine, however, because the agent is not approved for children in Germany, only after receiving written consent of parents. Alternatives are fluconazole and itraconazole. Onset and aggravation of tinea pedis during travel has its origin in a preexisting neglected fungal infection of the feet. In the tropics, exacerbations and secondary bacterial complications of tinea pedis develop under distinctly promoting conditions.
