Which are the symptoms of Cutis marmorata telangiectatica congenita?

TL;DR: Cutis marmorata telangiectatica congenita (CMTC) is a rare, non-hereditary vascular disorder characterized primarily by a persistent, net-like, violet-colored marbling of the skin present at birth. While the skin lesions often fade or improve significantly during childhood, patients should be monitored for associated anomalies affecting the limbs, eyes, or central nervous system.

What are the most common clinical symptoms of Cutis marmorata telangiectatica congenita?

The hallmark symptom of Cutis marmorata telangiectatica congenita is a reticulated (net-like) vascular pattern on the skin that appears at or shortly after birth. This pattern, known as livedo reticularis, typically affects the limbs, though it can also appear on the trunk or face. Unlike physiological cutis marmorata, which disappears when the skin is warmed, the vascular markings of Cutis marmorata telangiectatica congenita are persistent and do not fade with heat. In many cases, the affected area may also show skin atrophy (thinning) or ulcerations, particularly in the lower extremities.

How does the severity of Cutis marmorata telangiectatica congenita vary between patients?

The clinical presentation of Cutis marmorata telangiectatica congenita is highly variable, ranging from mild, localized skin changes to systemic involvement. Symptoms are often categorized by the extent of the skin lesions:

• Localized form: Affects only a specific limb or region of the body.


• Generalized form: Involves larger portions of the body, which statistically increases the risk of associated systemic anomalies.


• Asymmetry: Limb hypertrophy (overgrowth) or hemi-hypotrophy (underdevelopment) is a common associated symptom, occurring in approximately 50-70% of reported cases.

How do symptoms of Cutis marmorata telangiectatica congenita affect daily life?

For most of the 55 community members on DiseaseMaps.org living with Cutis marmorata telangiectatica congenita, the primary concern is the cosmetic appearance of the skin. However, when ulcerations occur—which are most common on the feet or lower legs—they can be painful and require careful wound management to prevent secondary infection. In cases where limb length discrepancy is present, patients may require physical therapy or orthopedic intervention to maintain mobility and comfort in their daily activities.

Do symptoms of Cutis marmorata telangiectatica congenita change over time?

A positive aspect of the natural history of Cutis marmorata telangiectatica congenita is that the skin lesions tend to fade or improve significantly as the child grows, often becoming nearly invisible by early adolescence. While the skin appearance usually improves, the structural or systemic anomalies, such as glaucoma or neurological differences, do not "outgrow" the condition and require ongoing, lifelong monitoring by a multidisciplinary medical team.

When should I seek immediate medical attention?

While Cutis marmorata telangiectatica congenita is generally a benign diagnosis, you should seek immediate evaluation if you notice signs of secondary skin infection (such as increasing redness, warmth, or pus in ulcerated areas) or if the child displays signs of developmental delay, seizures, or significant visual disturbances. Early screening for associated ocular or neurological conditions is standard practice for infants diagnosed with this condition.

Next steps

• Consult a pediatric dermatologist to confirm the diagnosis and establish a baseline for skin monitoring.


• Schedule an ophthalmology examination to rule out associated glaucoma, which can be present in a small subset of patients.


• Join the DiseaseMaps.org community to connect with other families and share experiences regarding management strategies.


• Maintain a log of any changes in skin appearance or limb development to share with your specialist at routine check-ups.
