Cutaneous Mosaicism

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.

Postzygotic Mutations

The simultaneous occurrence of a patch of light or dark brown hyperpigmentation with hypertrichosis (Becker's nevus) together with (usually ipsilateral) soft tissues hypoplasia (especially breast, in women) and underlying skeletal anomalies (i.e., vertebral hypoplasia, scoliosis, pectus carinatum or excavatum) represents the Becker's nevus syndrome (BNS) phenotype. It was first described (as a single cutaneous lesion) by Becker in 1949 and then associated with the surrounding musculoskeletal disorders. The syndrome has also been reported as pigmentary hairy epidermal nevus syndrome. Less than 100 cases have been reported in the literature, with a slightly higher incidence in females and only few familiar cases: paradominant postzygotic mutations and/or an androgen-dependent hyperactivation have been reported as the causes of the diseases.The extracutaneous lesions are congenital and nonprogressive, and the natural history of the Becker's nevus is the same as that of isolated nevi: in prepubertal boys, the pigmentation may be less intense and the hairiness may be absent or mild, as occurs in women, whereas in men, there is an increase of hairiness after puberty. The treatment is essentially cosmetic, and potential therapeutic options include electrolysis, waxing, makeup, or laser.
