Early detection of cutaneous melanoma by sequential digital dermatoscopy (SDD).

The early diagnosis and excision of cutaneous melanoma is essential for an improved prognosis of the disease. Besides the investigation of pigmented lesions with the unaided eye and conventional dermatoscopy, long-term sequential digital dermatoscopy has been shown to improve the sensitivity of melanoma detection, especially in high-risk patients. In addition to the static clinical and dermatoscopic assessment, the sequential digital dermatoscopy strategy helps to detect changes over time. This review summarizes the latest developments in the field of sequential digital dermatoscopy, describes current strategies for the selection of patients and lesions to monitor, and suggests objective criteria that should lead to an excisional biopsy.
