What is Cutis marmorata telangiectatica congenita?

Cutis marmorata telangiectatica congenita is a rare congenital vascular disorder that usually manifests in affecting the blood vessels of the skin. The condition was first recognised and described in 1922 by Cato van Lohuizen, a Dutch pediatrician whose name was later adopted in the other common name used to describe the condition – Van Lohuizen Syndrome. CMTC is also used synonymously with congenital generalized phlebectasia, nevus vascularis reticularis, congenital phlebectasia, livedo telangiectatica, congenital livedo reticularis and Van Lohuizen syndrome.

It should not be confused with the more general term "cutis marmorata", which refers to livedo reticularis caused by cold.
