PHACE without face? Infantile hemangiomas of the upper body region with minimal or absent facial hemangiomas and associated structural malformations

Abstract

Infantile hemangiomas can be associated with congenital anomalies such as PHACE syndrome with facial hemangiomas and genitourinary and spinal anomalies in the setting of lower body hemangiomas. We describe five infants in whom segmental hemangiomas involving the upper torso and extremities with absent or small facial hemangiomas were associated with structural anomalies similar to those reported with PHACE syndrome, including three with structural arterial anomalies of the subclavian arteries, three with aortic arch anomalies (right sided or narrowed arch), two with congenital heart disease (atrial septal defect and ventricular septal defect; tetralogy of Fallot), one with a retinal scar, and one with a sternal defect (scar). Two of five had small facial hemangiomas of the lower lip, but none had large segmental hemangiomas of the face. Three of five would have met diagnostic criteria for PHACE but lacked a facial hemangioma of 5 cm in diameter or greater. Patients with segmental arm and thorax hemangiomas may have associated structural abnormalities with overlapping features of PHACE, suggesting that a similar syndrome can occur in this clinical setting.
