Dr Metry at the Texas Children's Hospital is a pediatric dermatologist and a major researcher in the field of vascular anomalies. She has a vascular anomalies clinic which coinsists of a multi-disciplinary team who will completely evaluate your child. YOu need to get to a Vascular Anomalies team because as Rachel stated your child is at risk of other internal hemangiomas and related conditions. A referral to the Vascular Clinic would be your best option. Heamatology is part of the team but she will need to be assessed by the team.
Hope this helps, please keep us updated.
