Phlebectasia is an abnormal dilatation of an isolated vein, may affect any vein, and is usually asymptomatic. When the internal jugular vein is involved, it presents as a cervical swelling that can mimic the signs of either pharyngocele or a laryngocele and, because of its rarity, is frequently misdiagnosed. We describe 2 cases of phlebectasia of internal jugular vein in children with voice change in one of them. No treatment is necessary for this benign, self-limiting condition. Clinical features, diagnosis, treatment options, and a review of the literature about this rare venous lesion are presented.
