Juvenile systemic scleroderma. 
Systemic scleroderma in children is very rare and is considered similar to adult-onset disease.  In adults, new etiopathogenetic and therapeutic approaches have emerged in recent years.  For instance, it has been shown that microchimerism could play a role in disease pathogenesis and that immunoablation followed by stem cell rescue could be of potential therapeutic benefit.  There is also evidence that these new approaches can be of value for childhood-onset disease.
