Sebaceous hyperplasia is usually not a difficult clinical diagnosis when the yellow color is so pronounced like in this case. In dermoscopy we can see
aggregated white-yellow nodules , surrounded by branching vessels that extend towards the center of the lesion without crossing it: these
crown vessels (
radial wreath-like) are typical of the vessels observed in
sebaceous hyperplasia.
The thicker vessels around the lesion are couperosis.
