Cutis Marmorata Telangiectatica Congeita (CMTC) | Treatments

Cutis marmorata telangiectatica congenita (CMTC) often fades on its own over the first year as your child’s skin matures and thickens. Your child’s doctor will probably recommend observation after making sure that no other abnormalities are present.

A device called a pulsed dye laser can destroy abnormal blood vessels (telangiectasias) that remain after the CMTC has faded. Pulsed dye laser is the gold standard of treatment for telangiectasias because it is highly effective, doesn't damage the surrounding skin and rarely causes scarring. Your child's doctor can explain pulsed dye laser therapy and its side effects.

In very rare cases, CMTC can affect the growth of your child’s limb (usually the leg), causing one leg to grow faster or slower than the other. Should your child develop this or any other complications related to CMTC, we’ll refer her to the appropriate specialists within Boston Children's to design a treatment plan.

What is the long-term outlook for my child?

CMTC typically improves on its own. If it fades, it does not return.

After diagnosis and/or treatment, your child's physician and other members of your care team will develop a schedule of follow-up visits. The main purpose of these follow-up appointments will be to ensure that the CMTC is not affecting the growth of your child’s limbs.

While there are no lasting effects of CMTC, as your child gets older, she may be uncomfortable with the skin lesion, especially if it’s in a prominent location such as on the face or neck. Our counselors can help your child deal with the psychological and social issues related to having a birthmark.
