Summary

A multitude of developmental abnormalities affects the skin. Some of them are easily visible, others are unimpressive or hidden and can therefore remain unnoticed for a while. A few anomalies, such as the transverse nasal line and precalcaneal congenital fibrolipomatous hamartoma, are merely an insignificant freak of nature but most are at least potentially associated with underlying conditions, such as cranial or spinal dysraphism, or complex syndromes, for example branchial arch malformations. The purpose of the chapter is to provide the paediatric dermatologist with profound knowledge to differentiate between harmless negligibilities and cutaneous markers of serious developmental failures. The latter may deserve rapid diagnostic evaluation and treatment to prevent grave consequences.
