Seborrheic keratosis (SK), lichen planus-like keratosis (LPLK), and solar lentigo (SL) are common benign skin lesions. These lesions are frequently seen adjacent to each other or can arise from one another. They can sometimes be difficult to differentiate despite having distinct histopathological features.
We evaluated dermoscopic images of 80 skin lesions to confirm the term 'benign keratosis' is useful for an undifferentiated SK/LPLK/SL where there are overlapping clinical and dermoscopic characteristics.
Clinical and dermoscopic images were sourced from a teledermoscopy service database of 13,000 lesions in 7,000 patients. The database was queried for SK, SL or LPLK in sun-exposed sites. Each lesion was evaluated based on specific dermoscopic criteria and the results analyzed.
Lesions were identified with mixed clinical and dermoscopic criteria of SK and SL, and in some, dermoscopic criteria for LPLK were also present.
This study highlights the relationship between these lesions. We confirm the term 'benign keratosis' is useful for mixed lesions or for those that are difficult to classify.
脂溢性角化病（SK）、扁平苔藓样角化病（LPLK）和日光性雀斑样痣（SL）是常见的良性皮肤病变。这些病变经常彼此相邻出现，或者可能由一种病变发展为另一种。尽管它们具有不同的组织病理学特征，但有时仍难以区分。
我们评估了80例皮肤病变的皮肤镜图像，以确认“良性角化病”这一术语对于具有重叠临床和皮肤镜特征的未分化SK/LPLK/SL是否有用。
临床和皮肤镜图像来自一个远程皮肤镜服务数据库，该数据库包含7000名患者的13000个病变。在该数据库中查询暴露于阳光下部位的SK、SL或LPLK。根据特定的皮肤镜标准对每个病变进行评估，并对结果进行分析。
通过SK和SL的混合临床和皮肤镜标准识别出病变，并且在一些病变中还存在LPLK的皮肤镜标准。
本研究突出了这些病变之间的关系。我们确认“良性角化病”这一术语对于混合性病变或难以分类的病变是有用的。
