Digital dermatoscopic follow-up of 1027 melanocytic lesions in 121 patients at risk of malignant melanoma.

Objective: The aim of the presented prospective study was to use a digital dermatoscopic system to follow-up patients with multiple melanocytic naevi, and to evaluate the frequency and character of dermatoscopic changes.

Methods: We monitored selected melanocytic lesions with the use of a 6-month follow-up interval between check-ups. We searched for changes in size, shape, symmetry, structure and colour.
