Limited scleroderma, or CREST syndrome, is one subtype of scleroderma — a condition that literally means "hardened skin."

The skin changes associated with limited scleroderma typically occur only in the lower arms and legs and sometimes the face and throat. Limited scleroderma can also affect your digestive tract.

The problems caused by limited scleroderma may be minor. Sometimes, however, the disease affects the lungs or heart, with potentially serious results. Limited scleroderma has no known cure, and treatments focus on managing symptoms and preventing serious complications.
