Identifying the Variants of Myositis.
There are a few different forms of myositis. Review each of the conditions below to learn the unique differences and similarities among the clinical subtypes.
Dermatomyositis (DM)
Dermatomyositis (DM) is a form of myositis that can affect individuals of any age and gender, but is more commonly seen in women. It is characterized by muscle weakness, which develops gradually over time and is typically seen in the limbs closest to the core, such as the shoulders and hips. Elevated levels of creatine kinase (CK) in the blood are a common indication of muscle breakdown, but normal levels of CK can also be seen in some cases. One of the easiest forms of myositis to recognize, DM often presents with a visible skin rash caused by inflammation of blood vessels under the skin.
