- Morphea—Skin lesions are firm, at times oval, whitish or brownish plaques, surrounded by a purplish ring. Different types include:
- Plaque morphea—superficial lesions usually confined to the dermis
- Generalized morphea—individual plaques multiply or merge and are present in 2 or more sites
- Bullous morphea—lesions form blisters
- Skin lesions appear as hardened streaks or lines along the arms, legs, or forehead.
- May also involve subcutaneous tissue, muscle, and bone.
- A gradually progressing form of scleroderma that initially causes skin thickening, most commonly on the hands, forearms, feet, and lower legs
- Usually progresses to affect the internal organs.
- A more quickly progressing form of scleroderma that causes the skin to thicken throughout the body.
- It may also affect the internal organs.
- Sclerosis sine scleroderma—very rare form of scleroderma in which there are no skin manifestations, but the internal organs are affected.
