Large hemangiomas of the face can be associated with anomalies of the blood vessels of head and chest. The acronym PHACES indicates the association of Posterior fossa and other brain malformations, facial Hemangioma, Arterial anomalies, Coarctation of the aorta and other cardiac defects, Eye abnormalities and Sternal malformations. Study subjects will be recruited through the Pediatric Dermatology department in several cities. All patients age 0-1 year old of age, who present with large facial hemangioma (>22 cm^2) will be offered to participate in the study. Parents will be interviewed to obtain personal, medical, and family history.~Patients will undergo standard of care evaluation for facial hemangioma with risk of PHACE syndrome. This includes skin, eye and neurological examination, photograph, magnetic resonance imaging (MRI) of head/neck/chest, and lab tests requiring samples of blood, urine or stool. No other tests will be performed for participating in the study.~Lumbosacral hemangiomas of infancy (hemangioma in the lower back) can be associated with anomalies of the spine. Tethered cord syndrome indicates a condition caused by abnormally stretched spinal cord. Over time this condition can lead to neurological damage. Although often there are no symptoms until adulthood, it can become apparent during childhood. Common symptoms are: lower back pain, pain and weakness of the legs, walking problems, and bladder and bowel loss of control. Occult spinal dysraphism is the term used when the defect of the spine is hidden under normal skin. We noticed that infants with hemangioma in the lower back area are more inclined to present a hidden spine defect.~Study subjects will be recruited through the Pediatric Dermatology departments in several cities. All patients age 0-18 year old of age, who present with lumbosacral hemangioma (> 2.5 cm of diameter overlying the spine) will be offered to participate in the study. Parents will be interviewed to obtain personal, medical, and family history.~Patients will undergo standard of care evaluation for lumbosacral hemangioma. This includes skin, neurological examination, photograph, magnetic resonance imaging (MRI) of the back, lab tests requiring samples of blood, urine or stool. No additional tests will be performed only for participating in the study.
We are conducting a study on the possible presence of PHACES in children with large facial hemangiomas and lumbosacral hemangiomas of infancy (hemangioma in the lower back) . With this study we hope to better understand the risk of this syndrome and to develop guidelines for its evaluation and management.
