Revised 2-step algorithm for the dermoscopic diagnosis of skin lesions: Step 2

BCC: basal cell carcinoma; SCC: squamous cell carcinoma.

* Short-term monitoring, which consists of comparing digital dermoscopic images of the same lesion every 3 to 4 months, is only suitable for macular (nonpalpable) lesions; suspicious or atypical, nodular (palpable) lesions should be biopsied.
