Phlebectasia of jugular vein is an unusual mass in the neck in children. Between 1981-1989, 16 cases were admitted at our hospital, 14 of them were operated on ligation or excision, and 9 of the 14 patients have remained well 2-9 years following the operation. In 1 of the 2 patients who refused operation, the mass had increased in size after being discharged from the hospital. The etiology, diagnosis and treatment of the disease were discussed.
