Cutis marmorata telangiectatica congenita: clinicopathologic characteristics and differential diagnosis.

Cutis marmorata telangiectatica congenita is an uncommon cutaneous vascular disorder characterized by persistent cutis marmorata, telangiectases, and phlebectases. In addition to atrophic and/or ulcerated lesions, other vascular conditions may be observed. Cutis marmorata telangiectasia congenita usually occurs sporadically, typically is present at birth, and predominantly affects girls. Various associated congenital anomalies have been reported in approximately half of the patients with this condition.
