ABSTRACT
In case 1, a 34-year-old man had a pigmented lesion on his abdomen surrounded by an incomplete whitish halo (Fig 1, A and B). In case 2, a 59-year-old woman had a dark-brown papule on her leg, surrounded by a symmetric whitish halo. She claimed to have applied sunscreen to protect the "mole" (Fig 1, C and D).
