In their original publication, Haqq et al. classified the melanoma metastases in two groups due to their molecular profiles: five samples were classified as 'Type I' and fourteen as 'Type 2' based on a hierarchical clustering approach. Our result reinforced the view that the Type II melanomas metastasis is a pretty homogeneous group, we will present the results on the (Mskin, M-metastasis I)-plane. This means that now the P ave profile will not be obtained by averaging over the 19 metastases samples, but instead using only the 14 samples which have been labelled as 'Type II'. As such, we aim at revealing if Type I samples are indeed different in this plane, and if other clusters are also present. Figure 5 presents the results. The first fact worth commenting is the pronounced gap between normal skin samples and the nevi, primary, and metastatic melanoma samples as revealed by the Mskin measure. Note also that the M-skin is based on the average profile that of the normal samples, which indicates that no information about the profiles of metastasis are used, yet M-skin reveals that increasing values of this measure may be linked with a 'progression' from nevi to primary and metastasis melanoma profiles.
