Systemic sclerosis

Systemic sclerosis (SSc) is a very heterogeneous, chronic, rare, but socioeconomically important disease with a severe disease course and severe impairment of the quality of life of affected patients. Overview of the current state of research on the pathogenesis, diagnosis and therapy of SSc. A literature search was performed. The pathogenesis of SSc is not fully understood. ACR/EULAR criteria allow the diagnosis of early forms of SSc. Classification into limited cutaneous SSc and diffuse cutaneous SSc is of prognostic and therapeutic relevance. New organ-specific treatment options for SSc have led to improved quality of life and prognosis.
