Cutis marmorata

What is cutis marmorata?

Cutis marmorata is a condition where the skin has a pinkish blue mottled or marbled appearance when subjected to cold temperatures. It occurs in about 50% of children and is typically seen throughout infancy. Adults may also be affected. Rewarming usually restores the skin to its normal appearance.

Cutis marmorata telangiectatica congenita (CMTC) is a distinct vascular disorder that typically presents at birth or shortly thereafter. It has the same appearance as cutis marmorata and is more prominent in cold climates. However, improvement does not always occur with rewarming.

How do you get it and who is at risk?

The mottled appearance is caused by superficial small blood vessels in the skin dilating and contracting at the same time. Dilation creates the red colour of the skin whilst contraction produces a pale appearance. This phenomenon is most pronounced when the skin is cooled. Reasons why this happens is not fully understood but the following factors may be involved:

Although CMTC is a very rare disorder, 50% of these patients have one or more other associated congenital skin conditions. These include:

What treatments are available?

There is no treatment for CMTC as it is generally a benign condition that improves with age. Skin lesions often improve within the first 2 years of life as the skin matures.

Associated conditions such as glaucoma and other anomalies may require treatment.
