Objective To investigate the clinical features of tinea capitis in Guangzhou region.Methods A retrospective analysis of children with tinea capitis was conducted at Outpatient Department of Dermatology, third Affiliated Hospital of Sun Yat-sen University, Guangzhou (July, 2007-September 2013). The patients had a mean age of 6.0 (±3.6) years. Pathogens were determined by direct microscopic examination and fungal culture.Results Among 70 cases of clinically diagnosed patients with tinea capitis, 69 cases were positive for microscopic examination (99%) and 47 cases were positive for fungal culture (81%), 52 cases are Tinea alba (74%). The pathogenic stains mainly include 19 strains of Microsporum canis (40%), 13 strains of Trichophyton mentagrophytes (28%), 5 strains of Trichophyton violaceum (11%), 3 strains of Microsporum gypseum (6%). Other causative pathogens were found in 8 cases (15%). Among them, 4-7-year-old children with tinea capitis account for 50% (35/70).Conclusion Tinea alba is the main clinical type of tinea capitis in Guangzhou area.Microsporum canis was the most frequent causative pathogen. The main age rang of cases is 4-7 years old.
