Dermatoscopy of a minute melanoma.

We present a case report of a naevoid lentigo maligna (World Health Organisation level 1 melanoma) on the nose of a 46-year-old man. He was under surveillance because of a past history of two melanomas and developed a new lesion. The visible lesion was 1.6 mm in maximum diameter as measured by the scale on the dermatoscope footplate. The dermatoscopic structures present were limited to dots arranged asymmetrically. We believe that the fact that some of these dots were grey provided a useful clue to the diagnosis of melanoma.
