Scleroderma is a disease of the body's connective tissue. This tissue gives support and form to organs and structures in the body. The most body parts it affects are the skin and organs, such as the digestive system, heart, lungs, and kidneys. It happens when the immune system triggers cells to make too much collagen. It is then deposited in the skin and organs and causes hardening and thickening.

The cause is not known. Genes and the environment may play a role.
