Abstract: Objective: To determine the common pathogenic fungi and predisposing factors in children with tinea faciei of vellus hair. Methods: The patients with tinea faciei of vellus hair were collected from Apr 2014 to Mar 2019. The scales and vellus hair from the lesions were inoculated on Sabouraud dextrose agar and cultured at 27℃ for 2 weeks. The morphology and molecular biology of the pathogens were identified. Results: Sixty two strains of the pathogen were isolated, including 38 stains (61%) of Trichophyton mentagrophytes, 12 (19%) of Microsporium canis, 10 (16%) of Microsporium gypseumand and 2 (3%) of Trichophyton violaceum. Of the 73 patients, 62 cases had animal contact history, 45 cases used topical corticosteroid. All the patients were treated with topical terbinafine cream or bifonazole gel for 4-8 weeks. Among them some were also treated with oral terbinafine. All the patients were cured clinically and mycologically. Conclusion: The most common pathogenic fungi were Trichophyton mentagrophytes, followed by Microsporium canis and Microsporium gypseum. Contacting with pets is a risk factor for the infections.
