Lentigo maligna melanoma. A large lentigo maligna on the left cheek with the typical variegation in color. The lesion is flat, macular, and represents in situ melanoma. In the center of the irregular lesion there is a pitch-black nodule indicating a switch from the radial to the vertical growth phase and thus invasiveness: the lesion is now called lentigo maligna melanoma.
