First of all, we should know that localized scleroderma, also known as scleroderma, is a skin disease that is limited to the swelling of the skin and gradually hardens and shrinks. It can occur in many parts of the skin, such as scalp, forehead, waist, abdomen and limbs. Then the problem of its harm, first of all, if not only in the joint, can be early swelling, late atrophy, affecting the appearance. For example, the head will lose hair, and if it causes facial wrinkles, it may cause beautiful conditions, which is its harm. Then there are some key parts of development, such as hands, or some big joints, which can swell in the early stage and limit their activities, and scars and joint contracture may appear in the later stage, affecting the activities of joints. Localized scleroderma can be systemic, and it can accumulate visceral conditions, such as the heart or lungs or other nervous systems. Therefore, localized scleroderma still has its corresponding harm and should be treated as soon as possible.
