Abstract
Trichophyton indotineae is an emerging difficult to diagnose dermatophyte species associated with terbinafine resistance, which was initially described in South-Asian and Middle-Eastern countries. We report four cases of sexually transmitted dermatophytosis caused by T. indotineae in two female sex-workers, including one transgender woman, and two men who have sex with men. All four cases were acquired in Europe, highlighting the risk of pathogen spread through sexual contact outside initial endemic areas.
