Terra firma-forme dermatosis (TFFD) is characterized by dirt-like skin lesions that disappear after rubbing with alcohol. We describe the dermoscopic features of TFFD before and after alcohol swabbing in six patients. All patients showed similar dermoscopic appearance with large polygonal plate-like brown scales arranged together giving a mosaic pattern. These features disappear completely after isopropyl alcohol swabbing of the lesions. In conclusion dermoscopy can assist in the evaluation of terra firma-forme dermatosis and the dermoscopic evaluation of other dirty dermatoses is recommended in the future to compare findings with TFFD.
地状皮病（TFFD）的特征是皮肤病变类似污垢，用酒精擦拭后会消失。我们描述了6例患者在酒精擦拭前后TFFD的皮肤镜特征。所有患者的皮肤镜表现相似，有大片多边形板状棕色鳞屑排列在一起，形成镶嵌图案。用异丙醇擦拭病变后，这些特征完全消失。总之，皮肤镜有助于地状皮病的评估，建议未来对其他类似污垢的皮肤病进行皮肤镜评估，以便与TFFD的表现进行比较。
