Diagnostic Considerations

Also consider Kikuchi disease. [32]

Different connective-tissue diseases, especially early and particularly in childhood, may be challenging to diagnose. Months or years may pass before an accurate diagnosis can be made. [33] The 2013 American College of Rheumatology/European League Against Rheumatism Classification Criteria for Systemic Sclerosis (SSc) on defined subgroups of systemic sclerosis (SSc) and in mixed connective-tissue disease (MCTD) as an SSc-related disease were found to be more sensitive than the American College of Rheumatology 1980 criteria. [34] However, there remain concerns with regard to distinguishing systemic sclerosis from MCTD.
