Yellowish structures in dermoscopy comprise milia-like cysts (MLCs) and yellow lobular-like structures.
This study aimed at establishing the frequency of these features in BCC and at describing their dermoscopic details.
A retrospective analysis of digital dermoscopic images referring to 400 BCCs was performed. Images were evaluated for the presence of starry and cloudy MLCs and yellow lobular-like structures.
Among the 400 BCCs constituting our database, 40 presented yellowish structures (10%). "Yellow" BCCs were located more frequently on the head and were mainly of the nodular type. MLCs were observed in 7.75% of the cases (with a mean number of 4.9 MLCs per lesion), whereas yellow globules were noticed in 4.2% /ucodep of the lesions.
In the presence of BCC specific dermoscopic criteria, the observation of MLCs and yellow lobular-like structures should not prompt the dermatologist to exclude the diagnosis of BCC.
皮肤镜检查中的黄色结构包括粟丘疹样囊肿（MLCs）和黄色小叶样结构。
本研究旨在确定这些特征在基底细胞癌（BCC）中的出现频率，并描述其皮肤镜检查细节。
对400例BCC的数字皮肤镜图像进行回顾性分析。评估图像中是否存在星状和云雾状MLCs以及黄色小叶样结构。
在构成我们数据库的400例BCC中，40例呈现黄色结构（10%）。“黄色”BCC更常见于头部，主要为结节型。7.75%的病例观察到MLCs（每个病变平均有4.9个MLCs），而4.2%的病变观察到黄色小球。
在存在BCC特定皮肤镜标准的情况下，观察到MLCs和黄色小叶样结构不应促使皮肤科医生排除BCC的诊断。
