Abstract
Introduction: Tinea favosa, a dermatophytic infection primarily caused by Trichophyton schoenleinii, remains a notable dermatological concern. It is characterized clinically by yellowish cup-shaped crusts on the scalp, and these lesions can result in scarring or non-scarring alopecia. Case Presentation: Three cases of severe tinea favosa transmitted by T. schoenleinii in Afghan immigrants residing in Iran are presented. The prevalence of tinea favosa has declined in Iran, although in some parts of Iran, mostly in the northern cities, the prevalence is still fairly high. Environmental and socioeconomic factors are the most common causes of these differences and elevated prevalence in specific northern cities. Conclusions: The increasing trend of isolation of T. schoenleinii in the immigrant population in Iran should be considered a serious health problem that requires special attention, as it could be a potential source for the re-emergence of this dermatophytic infection in the region. This emerging trend necessitates specialized medical attention and raises broader questions about regional dermatological patterns and their consequences for public health. Tinea favosa epidemiology is subject to change due to shifting migration patterns, evolving socioeconomic conditions, increased international travel, and drug overuse. In light of these findings, we propose the following recommendations: We recommend training and educational programs for healthcare professionals, especially in regions with high immigrant populations, to enhance their ability to accurately diagnose and manage tinea favosa. We also recommend raising awareness about tinea favosa, its symptoms, and the importance of seeking timely medical attention. Targeting both immigrant communities and healthcare providers is crucial.
