Abstract

Abstract:

Objective The clinical characteristics of tinea capitis caused by Trichophyton rubrum were studied by the clinical analysis of 4 cases and the literature review of the recent 10 years. Methods According to clinical and mycology manifestation, 4 cases of tinea capitis caused by T. rubrum were diagnosed. We summarized their clinical characteristics, and review of the literatures in recent 10 years. Results The first 3 cases were preschool children, the fourth case was elderly female, and only 1 case had pet contact history. The three children's patients suffered from different degrees of tinea pedis and onychomycosis and were used to scratching feet; The fourth case suffered from diabetes mellitus and onychomycosis more than 10 years. The results of the fungal culture of the infected hair and nails scales were all T. rubum. After standardized oral antifungal drug treatment, all 4 patients were cured within 4-8 weeks. Literature review found that in the last 10 years, the frenquency of T. rubrum in tinea capitis was 0.6%-15.8% in domestic literature, and 0.8%-28.8% in English literature. The clinical manifestations were diverse, including erythema scale, alopecia, exudation and other lesions, kerion and black spots. Conclusion Tinea capitis caused by T. rubrum is not uncommon. Close contact infection with family members suffering from superficial fungal disease and self infection is an important mode of transmission of T. rubrum. Only by raising the awareness of different clinical forms of tinea capitis and using fungal examination as a routine examination method can help us to confirm more cases of tinea capitis.
