The Digital Dermoscopy allows the mapping of the signals (nevi) and scanning, in different enlargements, for later comparison of eventual changes.
By allowing the identification of a set of non-identifiable details to the “naked eye”, it increases the sensitivity in the diagnosis of malignant melanoma and is therefore often used as a skin cancer screening test.
Digital Dermoscopy is indicated in people with multiple nevi, especially atypical because it allows a rigorous follow-up and may allow the early diagnosis of melanoma by altering preexisting nevi or detection of de novo pigmented lesions. At the same time, by allowing a more correct distinction between “signs” that pose a danger to health and harmless “signs”, it avoids the unnecessary surgical removal of many benign lesions.
It is also used to aid in the diagnosis and therapeutic follow-up of multiple skin diseases.
