Cutis marmorata telangiectatica congenita (CMTC) is a rare condition that mainly affects the blood vessels of the skin. It is usually seen at birth or soon after.
CMTC looks like a purple / reddish, marble-like pattern on the surface of the skin. This pattern is similar to the fishnet-like blotches seen in young infants when they are cold. In children with CMTC, the marbling is more severe and always visible.
The marble-like skin pattern may be limited to a certain part of the body (see localized CMTC photo) and there may be slight depressions in the skin. CMTC also may be distributed over large areas of the body (see generalized CMTC photo.) CMTC can affect the arms, trunk and face, but usually occurs on the legs. The skin pattern may become more visible with vigorous movement, crying, or with exposure to the cold.
