DermoscopyDermoscopy is a non invasive diagnostic method. criteriameasure of how well one variable or set of variables predicts an outcome:

  • Aggregated white-yellowish globules or structures (cumulus sign) surrounded by crown vesselsRadial serpentine or arborizing vessels at the periphery of the lesion that radiate towards the center but do not cross the midline od the lesion. sebaceous hyperplasia (Groups of bending, scarcely branching blood vesselsare the part of the circulatory system, and microcirculation, that transports blood throughout the human body that extend towards the center without crossing it) [1][2] FiguresThis glossary term has not yet been described. 1 & 2.
  • Other vascular structuresThis glossary term has not yet been described. which can be seen in sebaceous hyperplasias are arborizing telangiectasias [3]. Figure 3.
