Analysis of the dermoscopic features of excised melanomas and their relation with tumor thickness in a tertiary hospital in Brazil.

In line with prior data, we identified an association between invasive melanomas and structures linked to fibrosis and tumor vascularity. Specifically, we noted the presence of atypical vessels, scar-like white areas, a blue-white veil, and shiny white structures. Also, a higher number of dermoscopic structures was seen in invasive melanomas. In thicker melanomas, we observed additional findings, including a higher frequency of radial streaming and a blue-white veil.
