​

• Sequential digital dermoscopy imaging (SDDI) involves the assessment of successive dermoscopic images to allow the detection of suspicious dermoscopic change in melanomas that lack dermoscopic evidence of melanoma at a particular time. We perform 3 months short-term digital monitoring and 6 months long-term monitoring.

• Short term computerized (digital) monitoring over a 3-month period has sensitivity of 94% and specificity of 83% for the diagnosis of melanoma. 

• 99.2% of lesions that are not changing in 3 months are benign. 96% of melanoma are changing after 3 months.

• Long term computerized monitoring over a 6-month period has a sensitivity of 97% for the diagnosis of melanoma.
