There are two main types of scleroderma: localized and systemic. Localized scleroderma only affects the skin, related tissues, and the muscles below the tissues. Systemic scleroderma affects the skin, the tissues beneath skin that lead to the blood vessels, and major organs. These forms of scleroderma are broken down further into subtypes, each with their own symptoms and level of intensity.
The two main scleroderma types are:
Localized scleroderma affects only certain parts of the body, while systemic scleroderma can affect the whole body. Both types have additional subtypes.

For some people, localized scleroderma can be serious and disabling. The two recognized types of localized scleroderma are:
