The significance of cutaneous spider naevi in children.
BACKGROUND
Cutaneous spider naevi are commonly considered to be a clinical sign of chronic liver disease. Little is known about their occurrence in children.


OBJECTIVE
To evaluate the occurrence of spider naevi in children with and without liver disease.


METHODS
The presence of spider naevi was investigated in 460 children, 34 of whom had chronic liver disease.


RESULTS
Of children without liver involvement, 38% had at least one spider naevus. The prevalence of spider naevi increased with age. Of control patients aged 5 to 15 years, 2.5% had more than five spiders present. Although eight of 10 children with cirrhosis had at least one spider naevus, only four of 34 children with chronic liver disease had five or more spiders present. Most spiders were on the hands and very few were >5 mm in size.


CONCLUSIONS
Children with liver disease rarely have large numbers of spider naevi. Although the finding of five or more spider naevi is more common in liver disease, many normal children also have one or more of these lesions.
