Sclerosis is the hardening or "induration" of skin.
Common causes of sclerosis include scarring following inflammation (which is also known as fibrosis), and/or ageing. Sclerosis is not just a skin lesion or skin condition, but can affect different areas of the body. The effects of sclerosis and the seriousness of their possible consequences depend on the area of the body that is affected and the extent of the sclerosis.
Sclerosis is included in this section because it is a type of skin lesion.
