An Hispanic male infant, born at term and without complications, was found shortly after birth to have a 7.4-cm reddish mass located just above the angle of his right mandible and extending inferiorly into his neck. There was no evidence of skin changes over the mass, and there were no other skin lesions. The results of laboratory tests were significant only for a mild to moderate thrombocytopenia (platelet count, 89 × 103/µL). Ultrasound of the neck revealed a large soft tissue mass with numerous vascular channels. A large draining vein was seen entering the internal jugular vein, and arterial feeding branches appeared to originate from the external carotid artery. A small phlebolith was also observed under the anterior portion of the mandible. No other intervention was recommended.
