Sebaceous hyperplasia

A 51-year-old woman consulted for yellowish- whitish papular lesions on her forehead.

Dermoscopy showed aggregated white-yellow nodules (see white circles), 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.

Aggregated white-yellow nodules and crown vessels ( radial wreath-like) are the 2 key signs for dermoscopic diagnosis of a sebaceous hyperplasia.
