General Discussion

Cutis marmorata telangiectatica congenita (CMTC) is a rare inherited disorder characterized by discolored patches of skin caused by widened (dilated) surface blood vessels. As a result, the skin has a purple or blue "marbled" or "fishnet" appearance (cutis marmorata). In some affected individuals, ulcerations or congenital skin defects (aplasia cutis) can be present. The latter association can be part of Adams-Oliver syndrome.. Additional associated abnormalities have been reported including pink or dark red, irregularly shaped patches of skin (nevus flammeus); loss of muscle tissue (wasting) on one side of the body (hemiatrophy); elevated fluid pressure within the eye (glaucoma); and/or undergrowth (hypotrophy) of one leg. However, many if not all of those cases represent forms of Klippel-Trenaunay syndrome or related disorders, in particular Cowden's disease. The most common association of true CMTC is with soft tissue (subcutaneous fat and muscle) hypoplasia. The disorder formerly known as macrocephaly-cutis marmorata telangiectatica congenital (M-CMTC) is a distinct genetic disease and is now called macrocephaly-capillary malformation (M-CM/MCAP) Virtually all cases of CMTC occur randomly for no apparent reason (sporadically). It is thought that CMTC represents a form of genetic mosaicism.
