title: [Salmon patch: a descriptive study].
abstract: OBJECTIVE
  salmon patch is a congenital venous malformation that usually affects the midline. Although it is very common, few studies have analyzed its prevalence or predisposing factors. The aim of this study was to determine the prevalence and clinical characteristics of salmon patch in a group of newborn infants from a health care area in northwest Spain and to assess its association with neonatal and maternal variables.
  
  
  METHODS
  a descriptive study was undertaken of live newborn children seen in the neonatal unit of the Department of Pediatrics at Hospital Arquitecto Marcide, Ferrol, Spain between May 1, 2008 and January 31, 2009. The study protocol included collection of data on neonatal variables (including gestational age, sex, ethnic origin, weight, and presence and anatomical site of salmon patch) and maternal variables (including age and number of previous pregnancies).
  
  
  RESULTS
  of the 600 newborn infants included in the study, 59% had salmon patches. The most commonly affected sites were the nape of the neck (226 infants, 37.6%) and eyelids (211 infants, 35.1%). In a number of cases, more than one part of the body was affected. There was a higher prevalence of salmon patch in full-term or post-term births, in girls, white children, heavier children, and infants born to mothers aged between 30 and 34 years or who had not been pregnant previously.
  
  
  CONCLUSIONS
  salmon patch occurred most frequently on the nape of the neck, the eyelids, and the glabella. Its prevalence was associated with certain neonatal and maternal factors.
