Diagnosis of Systemic Sclerosis (SSc)
Target population for these criteria:
The following decision tool is applicable to a patient being considered for a Systemic Sclerosis study.
The criteria are not applicable to patients having a systemic sclerosis-like disorder that better explains their manifestations, such as nephrogenic sclerosing fibrosis, scleredema diabeticorum, scleromyxedema, erythromylagia, porphyria, lichen sclerosis, graft versus host disease, and diabetic chierarthropathy. Patients with Skin thickening sparing the fingers are also not classified as having SSc.
