ABSTRACT

In India, in 2018, Trichophyton indotineae was isolated from a series of severe cases of tinea corpus and/or tinea cruris (skin lesions were extensive, highly inflammatory, sometimes pruritic and with a chronic relapsing course). It was thought that this anthropophilic fungus was endemic to India, and that the cases reported in other countries were imported from Asia; however, there are currently reports of autochthonous cases in different countries such as Germany. T. indotineae has emerged causing concern in the dermatological clinical area, since, although it is not a lethal pathogen, it is easily transmitted from person to person and is usually highly resistant to terbinafine, one of the first-line antifungal treatments of dermatophytosis. Furthermore, since it is phylogenetically related to T. interdigitale and T. mentagrophytes, its identification by conventional phenotypic methods is impossible, therefore molecular methods are required. Dermatologists must be attentive to the presence of T. indotineae to know its local transmission, in order to provide the most appropriate therapeutic management to patients, as well as to further elucidate the epidemiology of this emerging fungus.
