White Rosettes in Dermoscopy

Background: White rosettes structures seen during dermoscopic examination was thought to be specific to actinic keratosis, however this view gradually changed towards a wider one explaining that they are the result of reflection of polarized light by various keratinous structures, hence visualized in a variety of skin conditions. Objective: Documenting the non-specificity of the dermoscopic white rosettes structures in the diagnosis of actinic keratosis. Methods: Documentation of 12 cases with white rosette structures seen on dermoscopic examination using the DermLite II Pro and 10X optical zoom by Samsung S4 Zoom camera. Conclusion: Dermoscopic white rosettes though most frequently seen in actinic keratosis, are non-specific in their diagnosis.
