Trichophyton indotineae infections and other severe or antifungal-resistant dermatophytoses

Dermatophytosis (ringworm, tinea, jock itch, athlete’s foot) is a very common and typically minor infection of the skin caused by dermatophyte fungi.¹ In the past decade, severe or antifungal-resistant dermatophytoses have become a global public health concern, including in the United States.

The AAD has assembled resources on Trichophyton indotineae and other severe or antimicrobial-resistant dermatophytes. These resources include information sheets on disease recognition, diagnosis, and treatment options, but do not constitute a clinical guideline. The AAD/ILDS emerging diseases registry helps to gather information on severe or antimicrobial-resistant dermatophytosis cases.² This content was developed by the Academy’s Emerging Diseases Task Force and Avrom S. Caplan, MD, FAAD.
