Cutis marmorata telangiectatica congenita (CMTC) is a rare, deep purple, marble- or net-like birthmark. It is mostly cosmetic, and while it is present at birth, it fades considerably over a child's first year.

  • It forms as a result of abnormal blood vessels (a.k.a. a vascular anomaly).
  • CMTC poses little health risk and rarely needs to be treated; less than one percent of children who have CMTC receive any treatment for it.

How Boston Children's Hospital approaches cutis marmorata telangiectatica congenita

The Vascular Anomalies Center at Boston Children's takes an interdisciplinary approach to care with every child they see. While cutis marmorata telangiectatica congenita is typically only a cosmetic issue, on your first visit to clinic, several VAC specialists will often review you child's case at the same time. Our experience in treating numerous patients with CMTC gives us the depth of knowledge about what symptoms to look for and how to plan treatment accordingly. 

Once a diagnosis and the extent of the disease is confirmed, the team works with you to develop and carry out a comprehensive and coordinated care plan that matches your child's specific needs. The team brings the expertise of other Boston Children's departments and services as necessary to provide your child with the best care.
