[Persistent dermatomycosis due toTrichophyton indotineae].

is a recently identified dermatophyte that frequently causes extensive and persistent dermatomycosis, particularly tinea corporis, tinea cruris, and tinea faciei. The infection is frequently encountered in countries of the Indian subcontinent and surrounding areas. In Europe, has mainly been detected in patients with an epidemiological link to the aforementioned regions. Unlike dermatomycoses caused by other dermatophyte species, infections caused by often exhibit treatment failure with commonly prescribed antifungal drugs. Reduced susceptibility to terbinafine is often observed in . In addition, reduced susceptibility to itraconazole has also been reported. Due to the extensive and persistent nature of the infection, as well as the reduced susceptibility to antifungal drugs, international experts recommend aggressive treatment of using a combination of oral and topical antifungals. Susceptibility testing may be warranted to guide treatment decisions. Early recognition of infections is crucial to prevent prolonged recurrences.
