A yellowish lesion

A 70-year-old woman consulted for this small lesion on her right upper lid.

Dermoscopy revealed:

• a yellow clod pattern
• vessels arranged in a radial arrangement 

typical of a sebaceous hyperplasia

Sebaceous hyperplasia

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.

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.
