A Minute ‘Ugly-Duckling’ Pigmented Lesion on the Arm of a 60-Year-Old Caucasian Female

A 60-year-old woman, with phototype III skin and with no previous family or personal history of melanoma, presented to our department for a total skin check-up. One of his relatives, who was a physician, detected a 1-mm dark pigmented macule on the right arm that had been previously unnoticed by the patient. The patient had a moderate number of melanocytic nevi, predominantly macular. 10×-magnification dermoscopic imaging showed homogeneous pigmentation. 40×-magnification dermoscopic showed a central pigmented dark blotch, and surrounding pigmented dots and apparent peripheral streaks.
