ABSTRACT
Dermoscopically, sebaceous hyperplasia shows a pattern composed of the presence of aggregated white-yellowish globules in the center of the lesions with a surrounding crown of vessels (Figures 7.55-7.61).(3-7) The central aggregated white-yellowish structures or globules, showing a sharp difference from surrounding skin, were defined by Bryden et al. (3) as “cumulus sign,” a descriptive sign, because these structures resemble the cumulus clouds and correspond histopathologically to hyperplastic sebaceous glands. Bryden et al. (3) and Oztas et al. (5) observed these
Figure 7.58 “Bonbon Toffee sign” is the association of a central umbilication surrounded by cumulus sign. We can also see a peripheral crown of vessels, characteristic of this tumor (X10).
