Cutis marmorata telangiectatica congenita
(CMTC) is a birth defect involving the skin and blood vessels. It is characterized by cutis marmorata
, and phlebectasia
(varicose vein). The skin findings most commonly occur on the legs, less commonly on the arms and trunk, and rarely do they involve the face and scalp. It is occasionally associated with skin ulceration or skin atrophy. The skin symptoms associated with classical CMTC generally improve with age.
CMTC can occur alone or along with a variety of other birth defects, particularly those involving undergrowth or overgrowth of the same arm or leg. Most cases are thought to be sporadic
(non-inherited), although rare cases have been observed in families.
