From March 2008 through February 2014, 80 patients aged 1-95 years (43 men and 37 women) were diagnosed with tinea faciei by a rural Japanese clinic. The affected sites were the cheek in 42 patients (52.5%), the auricles and area surrounding the auricles in 16 (20.0%), and the mandible in 12 (15.0%); 33 patients (41.2%) had concurrent ringworm in areas other than the face. Twenty-one patients (26.3%) had applied topical steroids to treat a rash. The pathogen responsible for tinea faciei was Trichophyton rubrum in 35 patients (43.7%), T. tonsurans in 19 (23.8%), T. mentagrophytes in 3 (3.8%), T. verrucosum in 2 (2.5%), T. violaceum in 2 (2.5%), Microsporum canis in 17 (21.3%), and M. gypseum in 2 (2.5%). Clinical symptoms were divided into three groups based on the severity of inflammation and the extent of lesions and scored in points. Anthropophilic dermatophytes resulted in a score of 1.82 points for the severity of inflammation and a score of 1.84 points for the extent of lesions while zoophilic dermatophytes resulted in a score of 2.14 points for the severity of inflammation and a score of 1.50 points for the extent of lesions. This indicates that anthropophilic fungi resulted in less inflammation and broader lesions, whereas zoophilic fungi resulted in more intense inflammation and smaller lesions. Patients who had applied topical steroids had a mean score of 1.90 points for the severity of inflammation and a mean score of 2.10 points for the extent of lesions. Patients who had not applied topical steroids had a mean score of 1.95 points for the severity of inflammation and a mean score of 1.59 points for the extent of lesions. The severity of inflammation did not differ significantly. However, lesions were significantly broader in patients who had applied topical steroids than in those who had not applied topical steroids (p < 0.04). The severity of tinea faciei is a useful index for the clinical diagnosis of tinea faciei.
