In the course of their migration the neural crest cells reach all parts of the developing embryo. The frst wave of the derivatives of these cells the melanoblasts and melanocytes harbour in the epidermis and hair follicles during the dorsolateral migration. A number of signal molecules and proteases play an important role in the course of melanocyte migration through the extracellular matrix. The Mongolian spots appear as a consequence of the transient inhibition of melanocyte migration and in the case of fnal obstruction the Ota-, or. Ito nevuses. The Blaschko lines based on cutaneous mosaicism are of great diagnostic importance and on the ground of these lines the blaschkitises can appear under the exogenous factors. The blaschkolinear acquired infammatory skin eruption (BLAISE) is an acquired infammatory process. One of its variants is the lichen striatus and the other is the blaschkitis. The blaschkolinear dermatoses can appear usually as a nevoid disease. The pathological development of the neural crest cells can induce pathological processes in other tissues of the body as well, which may appear in the form of the so-called neurocristopathies including approximately ffty manifestations. The knowledge of the diferent pigmentation forms as well as the pathological symptoms of neurocristopathies is of great importance for the clinican from a diagnostic point of view.
