Disease Profile

Cutis marmorata telangiectatica congenita

Prevalence estimates on Rare Medical Network websites are calculated based on data available from numerous sources, including US and European government statistics, the NIH, Orphanet, and published epidemiologic studies. Rare disease population data is recognized to be highly variable, and based on a wide variety of source data and methodologies, so the prevalence data on this site should be assumed to be estimated and cannot be considered to be absolutely correct.


US Estimated

Europe Estimated

Age of onset





Autosomal dominant A pathogenic variant in only one gene copy in each cell is sufficient to cause an autosomal dominant disease.


Autosomal recessive Pathogenic variants in both copies of each gene of the chromosome are needed to cause an autosomal recessive disease and observe the mutant phenotype.


dominant X-linked dominant inheritance, sometimes referred to as X-linked dominance, is a mode of genetic inheritance by which a dominant gene is carried on the X chromosome.


recessive Pathogenic variants in both copies of a gene on the X chromosome cause an X-linked recessive disorder.


Mitochondrial or multigenic Mitochondrial genetic disorders can be caused by changes (mutations) in either the mitochondrial DNA or nuclear DNA that lead to dysfunction of the mitochondria and inadequate production of energy.


Multigenic or multifactor Inheritance involving many factors, of which at least one is genetic but none is of overwhelming importance, as in the causation of a disease by multiple genetic and environmental factors.

Cutis marmorata telangiectatica congenita (CMTC) is a birth defect involving the skin and blood vessels. It is characterized by patches of marbled-looking skin (cutis marmarota), small widened blood vessels under the skin (telangiectasia) and varicose veins (phlebectasia).[1][2] The skin findings most often occur on the legs, but may also occur on the arms and trunk. The face is only rarely involved. CMTC usually only affects a specific area of the skin, although there have been a few cases of CMTC over the whole body. It may occasionally occur along with open sores (skin ulceration) or skin atrophy. The skin symptoms associated with CMTC generally improve with age.[3][4] 

CMTC can occur alone or along with a variety of other birth defects, particularly those involving undergrowth or overgrowth of the same arm or leg. Most cases are thought to be sporadic (noninherited), although rare cases have been observed in families.[3][4]


The symptoms of cutis marmorata telangiectatica congenita (CMTC) may be different from infant to infant. Some may be more severely affected than others. Not everyone with CMTC will have the same symptoms.

CMTC is generally present at birth (congenital). Infants may be born with:

Red or purple marbled looking patches of skin that don’t respond to warmth (cutis marmorata)
Clusters of blood vessels visible under the skin (telangiectasia)
Skin ulcers (open sores)
Limb size discrepancy

The skin findings are usually seen in on part of the skin on the lower limbs, but can be on upper limbs or trunk, and less often, on the face. CMTC is usually confined to one part of the skin, on one limb, or on one side of the body. In rare cases, CMTC covers the whole body. The skin symptoms of CMTC typically get better over time and there are no known long-term complications of this condition.[3][2]

CMTC can also be found associated with other birth defects or as part of other syndromes as well.[3] 

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

Cutis marmorata telangiectatica congenita


The exact cause of cutis marmorata telangiectatica congenita (CMTC) is not known. It is thought that a combination of factors may contribute to the development of this condition. These factors may include diet, viral infections, and genetic factors. In a few rare cases, CMTC may occasionally run in families.[3][


Cutis marmorata telangiectatica congenita (CMTC) is diagnosed based on a clinical examination of the signs and symptoms. Additional studies may be done to look for signs of other syndromes that include CMTC.[4]


There is no specific treatment for isolated cutis marmorata telangiectatica congenita (CMTC). The skin symptoms typically fade and become less noticeable by 2 years of age, and often completely disappear by adolescence.[3][4] If treatment is necessary, it is symptom specific and supportive.


Support and advocacy groups can help you connect with other patients and families, and they can provide valuable services. Many develop patient-centered information and are the driving force behind research for better treatments and possible cures. They can direct you to research, resources, and services. Many organizations also have experts who serve as medical advisors or provide lists of doctors/clinics. Visit the group’s website or contact them to learn about the services they offer.
