Glowing in the dark: case report of a clue-poor melanoma unmasked by polarized dermatoscopy

We report a case of a melanoma arising in a congenital-type compound nevus, which was excised because it was observed by both the patient and the treating dermatologist to have changed. Because the lesion was routinely photo-documented with both polarized and non-polarized dermatoscopy images prior...
