Description
A handheld optical instrument combining magnification and polarized or nonpolarized light to visualize subsurface skin structures, pigment networks, and vascular patterns; used to differentiate benign from suspicious lesions, guide biopsy decisions, and monitor lesion evolution. Dermatoscopy improves diagnostic accuracy for melanoma and other skin cancers when used with clinical judgment and serial imaging, and requires training in pattern recognition, image documentation, and integration with patient history. Portable digital dermatoscopes enable image capture for teledermatology and longitudinal comparison, while adherence to standardized terminology and referral thresholds supports timely specialist evaluation.
