Cutis marmorata telangiectatica congenita: clinical features in 35 cases.

OBJECTIVE: To evaluate the distribution of skin lesions, clinical features, and associated abnormalities in children with cutis marmorata telangiectatica congenita at onset and during follow-up.

DESIGN: Retrospective survey of the available medical data with an average follow-up of 1 year 5 months (range, 0-7 years).

SETTING: Pediatric Dermatology Unit (Department of Dermatovenereology) of the Sophia Children's Hospital in Rotterdam, the Netherlands.

PATIENTS: The diagnosis of cutis marmorata telangiectatica congenita was clinically established in 35 patients between July 1988 and February 1997. In 33 cases, the typical mottled, blue-violet pattern was present from birth and was readily visible at rest. In 2 cases, the skin lesions initially appeared less reticulated, mimicking a capillary malformation.

RESULTS: The skin lesions were almost generalized in 4 children (11%), whereas they were more localized in the other 31 children (89%). Associated anomalies, usually minor and sometimes questionable, were noted in 80% of the patients. Most patients showed a definite improvement of their mottled vascular skin lesions within 2 years. The lesions had totally disappeared, or only faded residual lesions remained.

CONCLUSIONS: We believe that cutis marmorata telangiectatica congenita is a relatively mild condition. The prognosis is usually good, with minor associated anomalies. Improvement of the mottled, vascular pattern is usually observed within 2 years. We recommend careful clinical examination of all patients to exclude any associated anomalies. Patients should be referred to a neurologist or an ophthalmologist only if symptoms are present or if vascular lesions are present around the eyes.
