Answer

JXG may be present at birth (in about 10%) but most often arises in infancy. Children younger than 6 months are more likely to have multiple lesions. [2] Zimmerman reported 64% of cutaneous lesions to be present by age 7 months and 85% before 1 year. Adult onset is reported infrequently. [3]
