title: [Vascular malformations as syndromic markers].
abstract: Vascular malformations are static lesions, generally present at the moment of birth, formed by displasic vessels that grow in proportion to the growth of the child. They show normal cell replacements that constitute genuine mistakes of morphogenesis. The absence of regression of these malformations implies that they remain throughout the lifetime. The terminology describing this type of lesions gave rise to confusion in the medical literature until the International Society for the Study of Vascular Anomalies adopted a classification based on the dominant vessel of the malformation in 1996. This classification distinguishes between simple and complex forms depending on whether they affect one or several types of vessel. Vascular malformations can show themselves as isolated lesions or can be associated with other lesions, constituting the guide sign or being the principal marker of some syndromic complexes. This paper describes the principal signs and symptoms of those syndromes in which a vascular malformation is the key that raises suspicion about the existence of other associated lesions.
