They can be separated into 2 main categories: 1) juvenile systemic sclerosis (JSSc), characterized by diffuse skin sclerosis involving many sites of the body together with internal organ involvement, and 2) juvenile localized scleroderma (JLS), characterized by circumscribed skin induration but no vascular or internal organ involvement.
