juvenile systemic sclerosis
Rare autoimmune connective tissue disorder causing skin thickening and organ involvement in children.
Full Definition
Juvenile systemic sclerosis (jSSc) is a rare, multisystem autoimmune connective tissue disease that affects children and adolescents, characterized by vasculopathy, immune dysregulation, and excessive collagen deposition. The condition presents with progressive skin thickening, Raynaud's phenomenon, and potential involvement of internal organs including the lungs, heart, kidneys, and gastrointestinal tract. Unlike adults, children with systemic sclerosis often have a more aggressive disease course with higher rates of renal crisis and pulmonary complications. Early recognition and multidisciplinary management are crucial for preventing irreversible organ damage and improving long-term outcomes.
Usage
Usage note: Distinguish clearly from localized forms of scleroderma in documentation.
