Cutis marmorata telangiectatica congenita.

Babies commonly present with skin anomalies at or shortly after birth. While physiological cutis marmorata is a frequently encountered condition, we report a rare entity that appears similar, but should not be confused with it. Cutis marmorata telangiectatica congenita (CMTC) is a rare, sporadic condition that presents at birth as a localised or generalised reticulated, blue-violet vascular network in the skin. The prognosis is usually good, with minor associated anomalies. Clinical improvement occurs within the first 2 years in most cases but the lesions occasionally persist.
