Scleroderma is an uncommon condition that results in hard, thickened areas of skin and sometimes problems with internal organs and blood vessels.
Scleroderma is caused by the immune system attacking the connective tissue under the skin and around internal organs and blood vessels. This causes scarring and thickening of the tissue in these areas.
There's no cure for scleroderma, but most people with the condition can lead a full, productive life. The symptoms of scleroderma can usually be controlled by a range of different treatments.
