In the last quinquennium, new data concerning specific melanoma subtypes have come to light. The dermatoscopic morphology of superficial spreading melanoma (SSM) has been extensively investigated in the literature. Atypical network, irregular dots, irregular globules, irregular streaks and irregular blotch correspond to histopathologic alterations at the level of the junction, blue-white veil and atypical vessels suggest intradermal growth, whereas regression structures, negative network and white shiny streaks might reflect junctional or dermal alterations. The list of melanoma specific criteria has been recently updated to include features that typify early melanoma, such as irregular hyperpigmented areas and prominent skin markings and features seen in melanoma on sun damaged skin such as angulated lines. Nodular melanoma lacks most of the aforementioned criteria and is typified by the coexistence of blue and black color, atypical vessels and pink color.
