Treatment-resistant dermatophytosis: A representative case highlighting an emerging public health threat

Treatment-resistant dermatophytosis caused by Trichophyton rubrum has emerged as a global public health threat, particularly in endemic areas like India. However, few, if any such cases, have been reported in the United States. We report a representative case and discuss our experience treating several patients with extensive T rubrum tinea corporis that persisted despite prolonged treatment with systemic and topical agents, including oral terbinafine. We have witnessed an increasing number of treatment-resistant cases in our clinic over the last 5 years, but to our knowledge, there are no reported cases in the United States.
