Seborrheic keratoses are the most common benign epithelial lesion in adults. Their dermoscopic features have been well described in the chapter above. The following schematic shows the most typical features.

Seborrheic keratoses are found with shades of colors that span light brown to dark brown. They can also have multiple shades of brown and areas of white within a single benign lesion. The darkest SKs can mimic melanoma clinically which makes the understanding of the dermoscopic features so important. [1][2][3][4][5][6]

There is no data on how SKs in darker skin compare to SKs in lighter skin, but many have observed that dark SKs are common in dark skin.
