Pathogenesis
The following list is not meant to be exhaustive but shall sign post readers to freely available peer-reviewed open access publications (mainly reviews) prepared in the last few years by world leaders from the field on important aspects concerning the pathogenesis of systemic sclerosis.

Classification Criteria
The classification of SSc has evolved over the last 30 years. Below are a list of key publications concerning the classification (including subsets) of SSc that have emerged over the last 4 decades.
1980 Criteria for the Classification of Systemic Sclerosis
(Arthritis Rheum 1980;23:581-90)
http://www.rheumatology.org/Portals/0/Files/Systemic%20Sclerosis%201980.pdf
The preliminary classification criteria of the ARA were somewhat restrictive requiring either the presence of proximal skin thickening (major criteria) or a combination of at least 2 minor criteria that included sclerodactyly, digital pitting scars and/or bi-basilar pulmonary fibrosis. These criteria were less successful at identifying early or limited forms of systemic sclerosis.
LeRoy and colleagues proposed subsets of SSc based on extent of skin involvement (limited versus diffuse cutaneous systemic sclerosis).

Early diagnosis: Criteria for the classification of early systemic sclerosis
(J Rheumatol 2001;28:1573-6)
http://www.ncbi.nlm.nih.gov/pubmed?term=PMID%3A%2011469464
In recognition of advances in serological markers of systemic sclerosis and microvascular disease, LeRoy and Medsger proposed criteria for the classification of early systemic sclerosis that required objective evidence of Raynaud’s phenomenon (clinically observed or on microvascular imaging assessment) plus either abnormal nailfold capillaroscopy OR a SSc-specific autoantibody. In the absence of objective evidence of RP, patients could be classified as SSc if they had subjective features of RP AND nailfold capillaroscopic features of SSc AND a SSc-specifc autoantibody (anti-centromere, anti-Scl-70, anti-U3 RNP, anti-fibrillin, anti-PM-Scl or anti-RNA Pol III).

In 2013, the ACR/EULAR classification criteria were published and have subsequently been extensively validated. The manuscript can be accessed below:
http://www.rheumatology.org/Portals/0/Files/2013%20ACR%20EULAR%20SSc%20Classification%20Criteria_Complete%20article.pdf
These criteria have largely superceded previous criteria although there may still be a role for LeRoy and Medsger’s classification criteria for early SSc and attempts are being made to develop classification criteria for “very early” disease (VEDOSS criteria requiring presence of Raynaud’s phenomenon, puffy fingers and anti-nuclear antibodies).
