Correctly classifying a lesion under dermoscopy depends on the ability to categorize a lesion as either melanocytic or not.
A 71-year-old man presented to clinic with 2 lesions on sun-damaged skin that were suggestive under dermoscopy of melanocytic lesions. The first lesion appeared to have a globular pattern (Figure 1A). The second lesion seemed to have a network pattern (Figure 1C).
