Dermatoscopy is the examination of the skin lesions with a dermatoscope, using skin surface microscopy. Dermatoscopy is mainly used to evaluate pigmented skin lesions. In experienced hands it can make it easier to diagnose melanoma.

Computer software can be used to archive dermoscopy images and allow expert diagnosis and reporting (mole mapping). Smart programs may aid in diagnosis by comparing the new image with stored cases with typical features of benign and malignant pigmented skin lesions.
