Other Skin Changes. The following skin symptoms may also occur:

Flat red marks, known as telangiectasis, may appear in various locations, usually the face, palms, lips, or the inside of the mouth.

In calcinosis, small white lumps form beneath the skin, sometimes oozing a white substance that looks like toothpaste. Calcinosis can lead to infections.
Small blood vessels at the base of the fingernails may be severely narrowed in some places, and may widen in other places. This is an indication that internal organs might be involved.
The entire surface of the skin may get darker over time, and contain patches of abnormally pale skin.
Hair loss may occur.
About 1% of patients have Sjögren syndrome, a group of symptoms that include dry eyes and dry mucus membranes (such as those in the mouth).
Inside the mouth, scleroderma can also cause changes that impair gum healing.

Changes in bones, joints, and muscles can cause the following symptoms:

Mild arthritis. The condition is usually distributed equally on both sides of the body.
Bone loss in the fingers. The destruction is not as severe as it is in rheumatoid arthritis, although the fingers may shorten over time.
Trouble bending the fingers, if the disease has affected the tendons and joints.
Muscle weakness may occur, especially near the shoulder and hip.

Complications in the Upper Digestive Tract.

Esophageal motility disorder develops when scarring in the muscles of the esophagus causes them to lose the ability to contract normally, resulting in trouble swallowing, heartburn, and gastroesophageal reflux (also known as GERD). Some experts believe that patients with severe GERD may aspirate (breathe in) tiny amounts of stomach acid, which in turn may be a major cause of lung scarring.
About 80% of patients also experience impaired stomach activity. A delay in stomach emptying is very common.
Some patients develop "watermelon stomach" (medically referred to as CAVE syndrome), in which the stomach develops red-streaked areas from widened blood vessels. This causes a slow bleeding that can lead to anemia (low red blood cell counts) over time.
There may be a higher risk for stomach cancer.
Problems with movement of the food (motility) through the intestines also develop. Patients may experience an increase in bacteria levels in their intestines as a result, and have trouble absorbing nutrients from foods through their intestines.
