BACKGROUND/OBJECTIVES: The aim of this study was to evaluate the morphological findings of lipidised dermatofibromas under dermoscopic observation.
Dermoscopic examination of 13 cases of lipidised dermatofibromas was performed to evaluate specific dermoscopic criteria and patterns.
The most frequently occurring dermoscopic features were as follows: (i) A yellowish homogenous pigmentation in all cases (100%); this pigmentation was total in 30.7%; (ii) White structures were seen in 46.1%, most of them were central white networks (38.4%); (iii) Pigment network was observed in 53.8%, most of them were peripheral delicate pigment networks (38.4%), but two cases showed an atypical pigment network; (iv) The presence of vascular structures was common (10 cases, 77%); (v) Regarding to dermoscopic patterns, five lipidised dermatofibromas (38.4%) showed a total yellowish homogeneous pattern; 38.4% an atypical pattern and 23.2% a 'central white network + peripheral delicate pigment network' pattern.
The dermoscopic recognition of a total yellowish homogeneous area or a yellowish colouration in the context of a dermatofibroma can be proposed to help suspecting a lipidised dermatofibroma.
背景/目的：本研究旨在评估脂质化皮肤纤维瘤在皮肤镜下的形态学表现。
对 13 例脂质化皮肤纤维瘤进行皮肤镜检查，以评估特定的皮肤镜标准和模式。
最常出现的皮肤镜特征如下：（i）所有病例均出现均匀的黄白色色素沉着（100%）；其中完全性黄白色色素沉着占 30.7%；（ii）46.1%的病例可见白色结构，其中多数为中央白色网状结构（38.4%）；（iii）53.8%的病例可见色素网，其中多数为周边纤细的色素网（38.4%），但有 2 例显示非典型色素网；（iv）血管结构常见（10 例，77%）；（v）就皮肤镜模式而言，5 例脂质化皮肤纤维瘤（38.4%）表现为完全性黄白色均匀模式；38.4%为非典型模式，23.2%为“中央白色网状结构+周边纤细的色素网”模式。
在皮肤纤维瘤的背景下出现完全性黄白色均匀区域或黄白色着色，可提示存在脂质化皮肤纤维瘤。
