Abstract

Trichophyton tonsurans is an anthropophilic dermatophyte that is not yet truly prevalent in Korea. Especially, cases of toe nail infection during childhood are very rare, and no cases have been reported prior to this report. We report a single case of tinea unguium due to T. tonsurans in a healthy child. A 7 year-old patient visited an outpatient clinic presenting with subungual hyperkeratosis of the 1st and 3rd Rt. toe nails, which had first presented at an age of 28 months, and no other symptoms. Numerous hyphae were evident on the KOH smear examination. A confirmative diagnosis of tinea unguium cased by T. tonsurans was made after culturing scales from the toe nail lesion. The patient is currently undergoing follow-up, after being treated with oral terbinafine hydrochloride, without a relapse in symptoms.
