Limited scleroderma, also known as scleroderma, is a skin disease with limited skin swelling and gradual sclerosis and atrophy. Clinical manifestations and preliminary diagnosis of scleroderma symptoms: 1. Scleroderma punctata mostly occurs on the upper chest, neck, shoulders, buttocks or femur. The damage is soybean to nickel-sized, white or ivory-colored clustered or linearly arranged spots, round, sometimes slightly depressed. When the lesion is active, it is surrounded by a purplish-red halo. The texture is hard in the early stage, but later it becomes soft or has the feeling of “parchment”. The lesions are slow to develop, expanding in all directions and fusing with each other or remaining unchanged. Some lesions may fade away, with local residual pigmentation of mild atrophy. 2. Plaque-like sclerosis is more common. It occurs most often on the abdomen, back, neck, extremities and face. Initially round or irregular light red or purplish red edematous patches, after weeks or months of expansion, up to 1-10cm in diameter or larger, yellowish or ivory color. The surface is dry and smooth, with wax-like luster, surrounded by a mild purplish-red halo, with leather-like hardness when touched, sometimes with capillary dilation. There is no local sweating and no hair. The hardness decreases after a few years and gradually atrophies with central pigment loss. The lesions may invade the dermis and superficial subcutis, but are still mobile. The number and location of lesions varies, with most patients having only one or a few lesions, sometimes symmetrically. The lesions can cause sclerosing atrophic patchy alopecia when they are on the scalp. 3, linear or band-like sclerosis skin sclerosis often along the intercostal nerve or one side of the limb in a band-like distribution, can also occur in the forehead near the middle to the scalp extension in the shape of a knife, local lesions are significantly depressed, often began to become atrophic, the skin is thin and not hard, varying degrees of adherence to the bone surface. Most frontal scleroderma appears alone, but in some cases it may be combined with lateral facial atrophy. The band lesions often involve superficial and deep subcutaneous layers such as subcutaneous fat, muscle and fascia, eventually sclerosing the underlying tissues and often causing severe deformities. When crossing the joint surface of elbow, wrist and finger, it can restrict joint movement and cause limb open-arch contracture and claw-like hand. 4.Pantoid scleroderma punctate, plaque and linear types of damage can be partially or completely combined, the damage is many, distributed in various parts of the body, but rarely involves the face, the damage often has a tendency to fusion, often combined with arthralgia, abdominal pain, neuralgia, migraine and mental disorders, and occasionally can be turned into systemic scleroderma. 5.Deep scleroderma Su and Person (1981) reported cases of deep sclerosis of lipid membrane and fascia, sometimes also invade the dermis and deep dermis and superficial muscles. Disabling total sclerosing sclerosis is another recently reported type of sclerosis that occurs in children from 1 to 14 years of age, mostly in girls. Inflammation and sclerosis of dermis, subcutaneous tissue, fascia, muscles and bones occurs, especially in the extremities, especially the extensor side, hands, feet, elbows and knees are flexion contracture, rarely invade the internal organs, no Raynaud’s phenomenon, patients can have sclerosing mossy lesions, other parts of the body can have typical scleroderma performance.
