A case of tinea nigra in children

Abstract

A 6-year-old girl presented with brown patches on her right palm that had persisted for 5 years. Based on clinical manifestations, dermoscopy, and fungal microscopy, the child was diagnosed with tinea nigra. Molecular sequencing confirmed the pathogen as Hortaea werneckii. The patient was successfully treated with the topical application of an antifungal ointment.
