L94.1: Linear scleroderma

You have hard patches on your skin.

This skin condition causes the hard patches to look like bands. The skin can no longer be moved in the affected places. Tissues under the skin such as muscles and bones can also change. The tissues can shrink and become thinner than it is normally. The affected parts of the skin may also become darker. The affected areas can look like deep furrows over time.

The hard areas are mainly found on arms and legs and on the head. However, they can be found all over the body. If arms and legs are affected, then the affected areas may no longer be able to move as well as they did before. The hands may also tingle or hurt.

The exact cause of this skin disorder is not yet known. However, what is known is that this skin condition changes the skin’s connective tissue. The skin’s connective tissue is firmer in the affected areas than it is normally and shrinks. Connective tissue is made up of fine fibers. It supports and strengthens the skin, for example.
