Objective To assess the age distribution of the tinea faciei patients, the most common causative dermatophytes and clinical presentation of tinea faciei. Methods The patients with tinea facie treated in Dermatological Clinic during the period Jan 2012-Jun 2012 were evaluated. The diagnosis was confirmed by microscopic examination of skin specimens and culture on Sabouraud 's medium with added chloramphenicol. Data of basic information, medicine histories and clinical characteristics from the 118 cases of tinea faciei were analyzed. Results Tinea faciei could occur in any age groups, however, could often been observed between 51 to 70 year old . Most frequently isolated dermatophytes are Trichophyton rubrum ( 68. 0% ) , Microsporum canis (20. 4% ) , Trichophyton mentagrophytes (9.7%) , Microsporum gypseum ( 1. 9% ) . Autoinoculation, contacting with infected pets and immoderate using of corticosteroid cream were the significant risk factors of tinea faciei. Using medical swab can enhance fungal smear and culture quality on the obvious inflammatory sites. Conclusion As tinea faciei was easily misdiagnosed; more attention should be given on mycological examination of skin specimens.%目的 探讨面癣的致病菌、临床特点、易感年龄等相关因素.方法 分析本院门诊2012年1～6月的真菌直接涂片镜检发现菌丝或孢子的面癣患者.记录患者的一般资料、有无动物接触史、有无并发其他部位浅部真菌病、用药史.取皮屑直接镜检的同时进行真菌培养鉴定.结果 面癣见于各年龄段,在51～ 70岁之间有一个年龄高峰.分离皮肤癣菌103株,包括红色毛癣菌70株(68.0％)、犬小孢子菌21株(20.4％)、须癣毛癣菌10株(9.7％)、石膏样小孢子菌2株(1.9％).合并其他浅部真菌病、使用激素类药物、动物接触史是面癣发病的重要因素.部分炎症明显的面癣使用医用拭子取材,可以提高真菌涂片和培养的质量.结论 不典型的面癣容易误诊,需要高质量的真菌镜检和培养,降低面癣误诊率.
