Objective: To describe the clinical and dermoscopic characteristics of superficial spreading melanomas, and to detect the differences between in situ and invasive 1-mm thick melanomas.
Methods: This was a cross-sectional study in which dermoscopic images of 58 melanomas, grouped according to their thickness, were evaluated.
