Objective  To explore the causative agents, clinical features, risk factors and treatment outcomes of tinea scrotum. 

Methods  A retrospective analysis was done on the clinical data of 24 patients with tinea scrotum in the Dermatology Department, Third Affiliated Hospital of Sun Yat-sen University, Guangzhou, from 2007 to 2017, including their basic information, clinical characteristics, causative agents, concurrent superficial mycoses at other sites, pathogenic bacteria and treatment outcomes. 

Results  All of the 24 patients were young adults with average age of 19.6 years old and average disease duration of 2.9 months. The most frequently isolated pathogen was Microsporum gypseum（62.5%）, follow by Trichophyton rubrum（29.17%） and Epidermophyton flocussum（8.33%）. Microsporum gypseum caused most of simple infection of tinea scrotum with typical white pseudomembrance-like lesions, while T. rubrum caused infections of multiple sites including scrotum. 

Conclusion  Tinea scrotum usually involves young adults, and M. gypseum is the most frequently isolated pathogen usually causing simple infection of tinea scrotum with typical clinical features.
