Variant of localized scleroderma usually occurring along the length of a limb or around the trunk. The lesions appear as linear areas of induration, the lilac ring being inconspicuous or only present at the advancing border. They are usually single and unilateral, although a hemiplegic distribution may also occur, involving half the body. Sometimes the lesions may extend to involve the underlying muscles, or even bone.
