INTRODUCTION: Tinea capitis is a dermatophyte infection of the scalp and hair that predominantly affects preschool children; however, adult cases have received increasing attention in recent years. This study aims to evaluate the epidemiological characteristics of adult tinea capitis in Hangzhou, eastern China.
MATERIALS AND METHODS: The epidemiological data of adult tinea capitis patients referred to the mycology laboratory of Hangzhou Third People's Hospital from 2012 to 2025 were evaluated retrospectively. The epidemiological profiles were collected and analyzed, mainly including the pathogen spectrum and the present potential risk factors.
RESULTS: A total of 176 adult tinea capitis were included. The sex ratio was 1:2.59, with 49 (27.8%) males and 127 (72.2%) females. Women over 45 years of age accounted for 102 cases (58%). A total of 130 strains (82.8%) were isolated from 157 adult tinea capitis cases that had fungal culture performed. Cases with negative cultures were excluded from pathogen analysis. The most common pathogens were Trichophyton violaceum (36 cases, 27.7%) and Microsporum canis (36 cases, 27.7%), followed by Trichophyton rubrum (29 cases, 22.3%). Anthropophilic dermatophytes accounted for 80 strains (61.5%). Notably, 59 patients (33.5%) had concurrent dermatophyte infections at other body sites.
CONCLUSION: This study indicates that adult tinea capitis patients were predominantly female, especially those over 45 years of age. The predominant dermatophyte were T. violaceum and M. canis, followed by T. rubrum. This study provides a scientific basis for the prevention and control of ATC in the Hangzhou region.
