Case in brief
A 5-month-old Vietnamese infant presented with tinea faciei caused by Trichophyton indotineae, likely transmitted from the mother. Identification of the fungal species was confirmed through sequencing, and antifungal susceptibility testing indicated susceptibility to terbinafine. The infant's lesions resolved after 4 weeks of treatment with 2% ketoconazole cream, with no recurrence noted at 3 months.
What made this case unusual
This case is notable for the identification of Trichophyton indotineae in an infant, a species associated with antifungal resistance and rarely reported in this age group.
Diagnostic / clinical pearl
Clinicians should consider Trichophyton indotineae as a potential cause of dermatophyte infections in infants, especially with maternal transmission.
Why it matters
The emergence of Trichophyton indotineae underscores the need for awareness of shifting dermatophyte species and their implications for antifungal treatment in pediatric patients.
