What features would you look for on dermoscopy to differentiate between causes of skin-coloured facial papules?
There was background sun-damaged skin characterised by erythema, pink-red pseudonetwork, unfocused blood vessels and white halo structures around yellow follicular openings.[1]
Summary
The lesion was examined with non-polarised contact dermoscopy (Figure 2). There was a pearly papule measuring 2 mm with branching blood vessels (arborising telangiectasia). The papule was abutting a hair follicle.
