(TUF-ted AN-jee-OH-muh) A rare, benign (not cancer) blood vessel tumor that usually forms on the skin of the arms and legs, but may also form in deeper tissues, such as muscle and bone. Tufted angiomas grow slowly and can spread to nearby tissue. Signs and symptoms may include firm, painful areas of skin that look bruised; purple or brownish-red areas on the skin; easy bruising; anemia; and abnormal bleeding. Tufted angiomas are most common in infants and young children. They are a type of vascular tumor.
