Facial non pigmented actinic keratoses (AKs) display 4 main dermoscopic features:
- erythema, with a pink-to-red pseudonetwork surrounding the hair follicles
- white-to-yellow surface scale
- fine, linear-wavy vessels surrounding the hair follicles
- hair follicle openings filled with yellowish keratotic plugs and/or surrounded by a white halo
These features combined to produce a strawberry’ appearance.
