is a disease of the body’s connective tissue. Connective tissue is found throughout the body, providing support and form for organs and structures. Scleroderma is thought to be an autoimmune disorder, a condition in which the immune system mistakes the body’s own tissue for a foreign invader, attacking and damaging it. Researchers believe that the immune system’s interaction with the connective tissue causes an overproduction of collagen, a tough, hard protein that makes up tendons, bones, ligaments, and scar tissue. When this collagen is deposited in various places throughout the body, it causes hardening and stiffening.
The most common areas of the body affected by scleroderma are the skin, blood vessels, joints, and internal organs, such as the heart, lungs, kidneys, and digestive system.
