Cutis marmorata telangiectatica congenita (CMTC) is an epidermal and blood vessel birth abnormality. Spots of blotched-looking skin (cutis marmarota), little expanded capillaries under the epidermis (telangiectasia), and varicose strands are all symptoms. The most typical site for skin changes in the legs, even if they might also arise on the chest and arms.
Cutis marmorata telangiectatica typically only covers a small region of the epidermis, even though it has been seen to afflict the entire body in rare circumstances. It may operate in combination with skin ulcers on rare occasions. With age, the skin issues linked with the disorder usually improve.
