Trichophyton indotineae (TI) has emerged as a novel dermatophyte species causing treatment recalcitrant skin infections. While the earliest reports came from India, TI has now spread to many parts of the world and is rapidly becoming a global health concern. Accurate identification of TI requires elaborate mycological investigations not in the domain of routine microbiology laboratories. Extensive, non-inflammatory and atypical presentations are commonly seen with this novel species. TI shows an alarmingly high rate of mutations in the squalene epoxidase gene leading to lowered invitro susceptibility to terbinafine...
