A 48-year-old woman presented with a 2-year-history of a red skin nodule with a blue-gray pigmented area at the 2 o'clock position on her left upper arm (Panel A). Dermoscopy showed an irregular, reddish, diffuse pigmentation, a focal regression with irregular brown-gray globules (corresponding to the blue-gray pigmented area), and a diffuse polymorphous vascular pattern (Panel B). Once the melanocytic nature of the lesion was clarified with dermoscopy, it was excised.
