Congenital Cutaneovisceral Angiomatosis

Congenital Cutaneovisceral Angiomatosis (CCVA), also known as Klippel-Trenaunay syndrome, is a rare vascular disorder that affects multiple organ systems. This condition is present at birth and primarily manifests as abnormal blood vessel growth in the skin, soft tissues, and internal organs condition characterized by the abnormal growth of blood vessels in the skin and internal organs.

Types

Types of Congenital Cutaneovisceral Angiomatosis:

1. Klippel-Trenaunay Syndrome (KTS): KTS is the most common type of CCVA. It involves the abnormal development of blood vessels, soft tissues, and bones. Individuals with KTS may have port-wine stains (flat red or purple birthmarks), varicose veins, and overgrowth of limbs. Affected organs can include the brain, eyes, and internal organs.
2. Sturge-Weber Syndrome (SWS): SWS is another type of CCVA that affects the blood vessels in the face, brain, and sometimes other organs. Common symptoms include a facial birthmark called a port-wine stain, eye abnormalities, seizures, and developmental delays.
3. Blue Rubber Bleb Nevus Syndrome (BRBNS): BRBNS is a rare type of CCVA characterized by multiple blood-filled lesions that resemble blue rubber blebs. These lesions occur in the skin, gastrointestinal tract, and other organs. Symptoms may include gastrointestinal bleeding, anemia, and iron deficiency.
4. Proteus Syndrome: Proteus syndrome is a complex disorder that causes overgrowth of skin, bones, and other tissues. It is characterized by asymmetric and disproportionate growth of various body parts. Individuals with Proteus syndrome may experience vascular malformations and develop benign tumors.
