Fig. 20.26 Nevus anemicus. Neurocutaneous syndrome.

Neurocutaneous syndromes (NCS), also known as phakomatosis, include a heterogeneous group of disorders characterized by abnormalities of both the integument and central nervous system (CNS). Most disorders are inherited as autosomal dominant conditions with variable penetrance, and are believed to originate from a defect in differentiation of the primitive ectoderm.( 1 ).

Phakomatoses refers to a group of neuro-oculo-cutaneous syndromes or neurocutaneous disorders involving structures arising from the embryonic ectoderm.These multisystem disorders involve the ectodermal structures like central nervous system, skin and eyes. The lesions have a variable severity. However, it has been subsequently noted that mesodermal and endodermal tissues too are involved.

Genetic Evaluation of Common Neurocutaneous Syndromes.

Neurocutaneous Syndromes. The neurocutaneous syndromes, including neurofibromatosis, Sturge-Weber-Dimitri syndrome, and tuberous sclerosis, are associated with vascular occlusive disease (81, 134, 191). Multiple distal branch occlusions with and without other lesions involving the carotid artery can occur in these patients.The term “neurocutaneous syndromes” was introduced by Yakovlev and Guthrie in 1931 to describe this group of disorders as “congenital malformations affecting more or less electively the ectodermal structures, ie, the nervous system, the skin, the retina, the eyeball and its contents; sometimes visceral organs are also involved” (Yakovlev and Guthrie 1931).About Neurocutaneous Syndromes. Neurocutaneous syndromes are disorders that lead to growth of tumors in various parts of the body. They're caused by the abnormal development of cells in an embryo and characterized by the presence of tumors in various parts of the body (including the nervous system) and by certain differences in the skin.


Neurocutaneous syndrome is a general term for disorders that affect the brain, spine and peripheral nerves. These life-long conditions lead to the growth of tumors in the spinal cord, brain, bone.Key points about neurocutaneous syndromes in children. Neurocutaneous syndromes are disorders that affect the brain, spinal cord, organs, skin, and bones. The diseases are lifelong conditions that can cause tumors to grow in these areas. They can also cause other problems such as hearing loss, seizures, and developmental problems.
