The localisation of the lesion is important, because the pigment network is different in various areas. If looking at a pigmented lesion on the face, there will be no regular network due to lack of of rete ridges. Instead there is a pseudo-pigment network due to perforations of the eccrine sweatglands (Fig.10 ®
) On hands and feet the papillary rete ridges create a linear pigment pattern with openings of eccrine sweat glands appearing regularly in the middle of the less pigmented tips (Fig.11 ®
). The railway-like pigment pattern should not be mistaken for radial streaming or pseudopods of a melanoma.
