A case of dermatophytosis with uncommon clinical manifestations by Trichophyton indotinea

Dermatophytosis are micro-organisms which can lead to skin diseases. In rare occasions they can have atypical skin manifestations, which could result in delay in diagnosis.  

 A 20-year-old Iranian boy was referred to our center with a 5-month history of circular, symmetrical, itchy crusted skin lesions on his groin. Direct microscopy, culture test and PCR-sequencing of ITS regions of the rDNA gene were conducted and showed T. indotinea as the causative agent. Based on antifungal susceptibility test oral pulse therapy with itraconazole 100 mg twice daily for 1 week combined with topical clotrimazole cream for 1 month was initiated, which cleared the lesions.

This case report is of significance since T. indotinea produces atypical skin lesions, as well as, multidrug resistance to antifungal agents.
