Abstract:

A 36-year-old female patient presented to our clinic with complaints of black dots on the scalp for more than 10 years. The signs of black dots, comma hair and corkscrew hair could be seen in the dermatoscope. Direct fungal fluorescence microscopic examination showed a large amount of spores. Culture on Sabouraud dextrose agar revealed purple colonies, short-thick septa hyphae and chlamydospores could be found on the slide culture. Trichophyton violaceum was identified as the causative phathogen by nrDNA ITS sequencing. Oral itraconazole(0.2g/d) was administered to this patient combined with topical application of ketoconazole lotion and terbinafine spray. After 4 weeks treatment, the patient was cured and was still in the follow-up now.

Key words: black-dot ringworm, dermatoscope, Trichophyton violaceum, itraconazole
