What is scleroderma?

Scleroderma is a rare, chronic disease of the immune system, blood vessels and connective tissue. 2.5 million people worldwide have scleroderma, and in the UK there are 12,000 people diagnosed.

It is an autoimmune condition, meaning the immune system becomes overactive and attacks healthy tissue in the body.

The name of the condition comes from the Greek, 'sclero' for hard, and 'derma' for skin. This hardening of the skin can be one of the first noticeable symptoms of the condition, as the body produces too much collagen.

This excess of collagen can affect the skin, joints, tendons and internal organs. It causes scarring and stops the affected parts of the body from functioning normally.

What are the symptoms of scleroderma?

The symptoms of scleroderma vary for each person, and the severity depends greatly on which parts of the body are affected.

Usual symptoms include hardening of the skin, swelling of the hands and feet, joint pain and stiffness and blood vessel damage leading to a physical over-reaction to cold or stress, called Raynauds' Syndrome.

There are two main types of scleroderma, 'localised' and 'systemic':

' Morphea' is the name given to localised patches of hardened skin that are smooth and shiny. Usually they appear on the trunk, but they can affect any part of the body. They are painless and there are normally no other problems or symptoms.

In ' Linear' scleroderma the skin affected is in a line, usually along an arm or leg. The skin appears shiny, miscoloured or scarred, and often feels tight and uncomfortable. In children, it has to be monitored carefully as the normal growth of limbs can be affected.

Systemic sclerosis

In this type of scleroderma the internal organs are affected as well as the skin. The heart, oesophagus, blood vessels, kidneys, lungs, blood pressure and digestive system can all be involved.

There are two kinds of systemic sclerosis.

People with limited systemic sclerosis have normally lived with Raynaud's syndrome for a long time. The condition progresses gradually, and usually only affects the face, hands, arms below the elbow, feet and legs below the knees - although the lungs and digestive system may be affected over time. Symptoms can include thickening of the skin, heartburn and problems with swallowing.

In diffuse systemic sclerosis, it is more likely that the whole body will be affected, and in some cases there can be potentially serious complications involving the heart, lungs and kidneys. Common symptoms include fatigue, joint pain, and stiffness.

How serious is scleroderma?

The impact scleroderma has on everyday life varies enormously from person to person. In some cases it can be very mild and easy to live with. For others it can cause serious physical disability and be life-threatening.

It depends a lot on which parts of the body are affected, and how. Read more about localised scleroderma and systemic sclerosis here.

With the right treatment, most people live long and productive lives with scleroderma. Find out more about managing scleroderma here.

Is there a cure for scleroderma?

There is currently no cure for scleroderma, but the condition can be managed well for most patients through a combination of drug therapy, physical therapy, surgery and self-management techniques.

At SRUK we support the latest research into treatment and a cure for scleroderma.

What causes scleroderma?

The cause of scleroderma is unknown. It is not contagious, so you can't catch it from someone or give it to anyone else.

There is some evidence of a genetic link to systemic sclerosis, although most people will not have a family member with the condition.

Who is at risk of scleroderma?

The condition is four times more common in females than males and during childbearing years, the percentage rises to ten females to one male.

Scleroderma usually begins between the ages of 25 and 55 and in most cases, it is preceded by Raynaud's.

It occasionally occurs in children and the elderly, but fortunately most types of childhood scleroderma are localised and only involve the skin. More information on localised scleroderma in children can be found here.


Although more than 95% of patients with scleroderma have Raynaud's, the chances of someone with Raynaud's developing scleroderma is very small - it is less than 2% in females and 6% in males.

The condition does not appear to be related to race, ethnicity or where you live.

I have just been diagnosed with scleroderma, what should I do next?

A diagnosis of a rare disease like scleroderma can be frightening and isolating. But it doesn't have to be. At SRUK, we strive to give support and advice to everyone who is diagnosed with the condition, and their family.

Find out more on our page for people who are newly diagnosed, or speak to someone today on our helpline – 0800 311 2756.
