There is no easy way to determine scleroderma, as the diagnosis of scleroderma requires a combination of evidence. Currently, scleroderma is categorized into limited and systemic scleroderma, with limited scleroderma being diagnosed on the basis of typical skin lesions and systemic scleroderma on the basis of the diagnostic criteria of the American College of Rheumatology. Scleroderma is a connective tissue disease characterized by localized or widespread hardening of the skin and progressive sclerosis of the internal organs, and is divided into limited and systemic scleroderma according to the extent of the lesions. Limited scleroderma can be diagnosed on the basis of typical skin lesions, including punctate, plaque, linear and generalized lesions. Systemic scleroderma is diagnosed based on the American College of Rheumatology diagnostic criteria. The primary criteria are symmetrical thickening, tautness, and sclerosis of the skin above the fingers and metacarpophalangeal joints, which may involve the entire limb, face, and neck and trunk. Secondary criteria are scleroderma of the fingers, bilateral pulmonary basal fibrosis, depressed scarring of the fingers due to ischemia, or loss of finger pad tissue. The diagnosis is made where 1 major or 2 minor criteria are present. If any of the above symptoms occur, it is recommended to go to the hospital in time to make a clear diagnosis and under the guidance of the doctor to carry out regular treatment as soon as possible.
