Cutis marmorata telangiectatica congenita: long-term follow-up, review of the literature, and report of a case in conjunction with congenital hypothyroidism.

Cutis marmorata telangiectatica congenita is an uncommon, generally congenital, cutaneous condition. The major skin findings are persistent, fixed cutis marmorata, telangiectasia, and phlebectasia; often, there is associated skin atrophy and ulceration as well. Significantly, two-thirds of patients have other congenital anomalies, although often minor ones. We report a series of eight children with cutis marmorata telangiectatica congenita, including one with associated congenital hypothyroidism, a relationship that has never before been noted.
