Reduced Visibility of Pigment Network Under Sub‐UV Reflectance Dermatoscopy Compared to Polarised Dermatoscopy: A Novel Diagnostic Clue to Differentiate Melanomas From Nevi

JEADV Clinical Practice, EarlyView.
ABSTRACT Background Melanoma accounts for more than 75% of skin cancer‐related mortality. Dermatoscopy is an evidence‐based technique for earlier detection, yet differentiating melanocytic lesions remains challenging. Sub‐UV reflectance dermatoscopy (sUVRD) uses purple light (405 nm) to visualise chromophore distribution in the skin.
