背景资料：皮肤纤维瘤在皮肤镜下的典型表现是中央呈白色瘢痕样斑片，周围呈精细的色素网。目的：分析皮肤纤维瘤在皮肤镜下的不同表现。方法：对2003年5月至2005年7月间发现的52例皮肤纤维瘤进行分析。疤痕样区域内的小球（38.5%）、线性/不规则隐窝（26.9%）、雀斑样网状色素沉着（23%）、均匀的蓝灰色色素沉着（5.9%）和白色斑块周围的圆形均匀区域（3.8%）是观察到的模式。此外，皮肤纤维瘤的萎缩性变异的皮肤镜特征进行了描述，这是在一个病灶（1.9%）。限制：无。结论：皮肤纤维瘤有各种皮肤镜的功能。其中，“线性，不规则的隐窝”是不寻常的，并在这项研究中描述。皮肤镜下均匀的蓝色色素沉着可能是诊断皮肤纤维瘤含铁血黄素变体的一个可能线索。
Background: Central white scarlike patch and a delicate pigment network at the periphery is the typical appearance of dermatofibromas on dermoscopy.Objective: We aimed to analyze the different dermoscopic appearances of dermatofibromas.Methods: Fifty-two dermatofibromas with dermoscopic features different from the classic type, which were detected between May 2003 and July 2005, were evaluated.Results: Globules in the scarlike area (38.5%), linear/irregular crypts (26.9%), lentigo-like reticular pigmentation (23%), homogeneous blue-gray pigmentation (5.9%), and erythematous homogeneous area surrounding the white patch (3.8%) were the patterns observed. In addition, dermoscopic features of an atrophic variant of dermatofibroma are described, which was seen in one lesion (1.9%).Limitations: None.Conclusion: Dermatofibromas have various dermoscopic features. Among them, "linear, irregular crypts" is not unusual and is described in this study. Homogeneous bluish pigmentation on dermoscopy may be a possible clue for the diagnosis of hemosiderotic variants of dermatofibromas.
