T. tonsurans is an anthropophilic dermatophyte causing several clinical variants of tinea capitis including the Kerion celsi that can be often unrecognised or confused with other lesions. We report a case of Kerion celsi caused by Trichophyton tonsurans in a child following an excoriation to the scalp caused by a fall in a public park. The use of multiplex PCR assay has enabled rapid diagnosis of tinea capitis from T. tonsurans with a result in less than 48 hours and therefore the possibility of quickly starting antifungal therapy. The patient had a complete recovery at the end of the antifungal treatment.
