The term Tinea Faciei (TF) designates a superficial dermatophyte infection of the glabrous skin of the face, characterized by clinical polymorphism. The aim of the present study is to assess epidemiologic, clinical, mycological, and therapeutic characteristics of TF in a Tunisian dermatology department.
This retrospective study examined the records of cases of TF observed in our dermatology department over the past 5 years (2003-2007).
Fourteen patients with TF were seen during the study period. The sex ratio (5 male/9 female) was 0.56. The average age of these 4 children and 10 adults was 22 years. While the clinical form was typical of TF in 10 cases, 4 patients had a clinical form modified by topical steroids (Tinea incognito). Direct microscopic examination showed hyphal elements in 12 cases, and the mycological culture was positive for 11. Five patients had Trichophyton Violaceum, and 4 T. Mentagrophytes.
TF is frequently misdiagnosed because of its variable appearance. Atypical forms known as tinea incognito are observed after modification of the dermatophyte infections by corticosteroid treatment. Our study included 4 cases of Tinea incognito. T. Mentagrophytes and T. Rubrum are the agents reported most frequently. Unusually, T. Violaceum was found most frequently in our series.
面癣（TF）这一术语指面部光滑皮肤的浅表皮肤癣菌感染，其具有临床多态性。本研究的目的是评估突尼斯某皮肤科门诊面癣的流行病学、临床、真菌学及治疗特征。
这项回顾性研究查阅了过去5年（2003 - 2007年）在我们皮肤科门诊观察到的面癣病例记录。
研究期间共诊治了14例面癣患者。男女比例为5:9，性别比为0.56。这14例患者中4例为儿童，10例为成人，平均年龄为22岁。10例患者的临床症状为典型面癣，4例患者的临床症状因外用类固醇而改变（隐匿型癣）。直接镜检在12例中发现菌丝成分，真菌培养11例呈阳性。5例患者感染紫色毛癣菌，4例感染须癣毛癣菌。
由于面癣外观多变，常被误诊。在皮质类固醇治疗改变皮肤癣菌感染后可观察到非典型形式，即隐匿型癣。我们的研究纳入了4例隐匿型癣病例。须癣毛癣菌和红色毛癣菌是最常报道的病原体。不同寻常的是，在我们的系列研究中紫色毛癣菌最为常见。
