Definition
By Mayo Clinic staffScleroderma (skleer-oh-DUR-muh) is a group of rare, progressive diseases that involve the hardening and tightening of the skin and connective tissues — the fibers that provide the framework and support for your body.
Localized scleroderma affects only the skin. Systemic scleroderma also harms internal organs, such as the heart, lungs, kidneys and digestive tract.
Scleroderma can happen to anyone at any time in any geographical area. However, the disease affects women more often than men and most commonly occurs between the ages of 30 and 50. Scleroderma can run in families, but in most cases it occurs without any known family tendency for the disease. Scleroderma isn't considered contagious, but it can greatly affect self-esteem and the ability to accomplish everyday tasks.
