How csn we differniate between limited and diffuse scleroderma?

Extent: Extent of skin involvement and whether or not other scleroderma complications are present.

See details: It is sometimes very difficult but truly limited disease is generally limited to the skin and has no internal organ involvement, typical hand changes or raynauds.

Skin involved: Scleroderma is divided in to localized types and systemic types. Localized forms (morphea, linear) have a few patches or lines of affected skin. Systemic types (limited, diffuse) involve more widespread areas of skin and may affect internal organs. The distinction between limited scleroderma and diffuse scleroderma refers to the amount of skin involved.
