Sebaceous hyperplasia
From dermoscopedia
Sebaceous hyperplasia is a common and benign condition typically observed as single or multiple yellowish, soft, small papules commonly occurring on the forehead, cheeks and nose of middle aged adults or elderly people.
Dermoscopy criteria
- Aggregated white-yellowish globules or structures (cumulus sign) surrounded by crown vessels (Groups of bending, scarcely branching blood vessels that extend towards the center without crossing it) [1] [2]
- Other vascular structures which can be seen in sebaceous hyperplasias are arborizing telangiectasias [3].
- Bonbon toffee sign: Association of a central umbilication or small crater surrounded by white-yellowish globules or structures [4].
- Occasionally, milia-like cysts may be present.
