Dermatomyositis is an uncommon inflammatory disease marked by muscle weakness and a distinctive skin rash.
Dermatomyositis affects adults and children alike. In adults, dermatomyositis usually occurs from the late 40s to early 60s. In children, the disease most often appears between 5 and 15 years of age. Dermatomyositis affects more females than males..
The exact cause of dermatomyositis is unknown, but the disease shares many characteristics with autoimmune disorders, in which your immune system mistakenly attacks your own body tissues.
Small blood vessels in muscular tissue are particularly affected in dermatomyositis. Inflammatory cells surround the blood vessels and eventually lead to degeneration of muscle fibers.
The most common signs and symptoms of dermatomyositis include:
· Skin changes. A violet-colored or dusky red rash develops, most commonly on your face and eyelids and on areas around your nails, knuckles, elbows, knees, chest and back. The rash, which can be patchy with bluish-purple discolorations, is often the first sign of dermatomyositis.
· Muscle weakness. Progressive muscle weakness involves the muscles closest to the trunk, such as those in your hips, thighs, shoulders, upper arms and neck. The weakness affects both the left and right sides of your body, and tends to gradually worsen.
There's no cure for dermatomyositis, but periods of remission — when symptoms improve spontaneously — may occur. Treatment can clear the skin rash and help you regain muscle strength and function

With dermatomyositis, areas affected by your rash are more sensitive to the sun. As a precaution, wear protective clothing or high-protection sunscreen when you go outside.
