Dermatomyositis is a very rare inflammatory disease which is characterized by the muscle weakness and allergic skin reactions such as for example skin rash. This disease is more common in women than in men, and usually happens in adults after they turn 40. If it occurs in children then the years between 5 and 15 are the risk years for this disease.

Dermatomyositis has many warning signs and symptoms. The most frequent symptom is the skin rash which is violet or dusky red and which usually appears on the face, back, chest, nails, elbows, and knees. Other symptoms of this disease include muscle weakness, dysphagia, fatigue, fever, as well as weight loss and problems with lungs and gastrointestinal tract.

Complications of dermatomyositis

Dermatomyositis must be treated on time, because it can cause some serious complications, such as muscle weakness complications, skin symptom complications and some associated conditions. Muscle weakness complications include problematic swallowing, aspiration pneumonia, problems with breathing, and gastrointestinalproblems.

Dysphagia or difficult swallowing occurs when the muscles in the esophagus are affected by dermatomyositis, thus leading to the loss of the weight and malnutrition. In some cases, this condition can even cause the entrance of saliva, food, or liquid in the lungs, which has as a consequence aspiration pneumonia. Shortness of breath may occur in the cases when the muscles of the chest are affected by dermatomyositis. Of gastrointestinal problems, the gastrointestinal ulceration and bleeding are very common. Some complications include infections of the respiratory and digestive tract and calcium deposits in the muscles skin and calcinosis or connective tissue.

Untreated dermatomyositis can cause some other complications such as Raynaud’s phenomenon, cardiovascular and lung disease, as well as cancer and some connective tissue diseases. Raynaud’s phenomenon is the medical term for the disease when the fingers, toes, nose, cheeks and ears become pale on low temperatures. Myocarditis or heart muscle inflammation may also occur as the result of the untreated dermatomyositis. Two other cardiovascular problems can also appear such as heart arrhythmias and congestive heart failure.

Interstitial lung disease may also happen along with dermatomyositis. Interstitial lung disease leads to the scarring of the lung tissues. The lungs thus become rigid and the person has the dry cough and problems withbreathing. One of the most serious complications that dermatomyositis can induce is cancer, which usually occurs three years after the diagnosis is set. The cancer of cervix, lungs, breasts, ovaries and gastrointestinal tract can develop. Lupus, rheumatoid arthritis, and Sjogren’s syndrome are some of the complications that can accompany dermatomyositis.
