Dermoscopically there are multiple grouped white-yellow clods, which are sometimes referred to as looking like the cumulus cloud formation. There are numerous vessels, none of which cross the midline. The diagnosis is consistent with sebaceous gland hyperplasia, as were the other lesions.
Differentiating dermoscopically between SGH and BCC is usually straightforward. The SGH on the left is comprised of separate white-yellow clods that are aggregated, and the vessels do not cross the midline. The BCC on the right is one solid 'gelatinous' structure, within which are fine branching vessels some of which may cross the centre. In this particular BCC there is also a blue clod.
