RESUMEN
Objective:To investigate the distribution of pathogenic fungi in patients with tinea capitis diagnosed in Xijing Hospital, Air Force Medical University in the past 10 years.Methods:A total of 871 outpatients or inpatients with tinea capitis were collected from the Department of Dermatology, Xijing Hospital from January 2011 to December 2020, and their clinical data and pathogen distribution were retrospectively analyzed. Pearson chi-square test was used to analyze differences in the pathogen distribution between children and adult patients with tinea capitis.Results:Of 871 patients with tinea capitis, 588 (67.5%) were males and 283 (33.5%) were females; 21 (2.40%) were aged less than 1 year, 266 (30.50%) aged 1 - 3 years, 352 (40.40%) aged 4 - 6 years, 187 (21.50%) aged 7 - 12 years, 4 (0.50%) aged 12 - 18 years, and 41 (4.70%) were aged 18 - 74 years. A total of 705 pathogenic strains were isolated from these patients, including 599 strains of Microsporum canis (85.0%) , 52 strains of Trichophyton mentagrophytes complex (7.4%) , 27 strains of Trichophyton tonsurans (3.8%) , and 18 strains of Trichophyton violaceum (2.6%) . Among the pathogenic fungi of tinea capitis, the proportion of Trichophyton violaceum was significantly higher in adults (8.8%) than in children (2.2%, P = 0.048) . Conclusions:In the past 10 years, the patients with tinea capitis in the Department of Dermatology, Xijing Hospital were mainly children aged 1 - 6 yearswhile adults, and adult patients with tinea capitis were uncommon. The main pathogen of tinea capitis was Microsporum canis, followed by Trichophyton mentagrophytes complex.
