Dermatomyositis is an autoimmune inflammatory myositis, which although having a predilection for the upper aspects of the lower limbs, may involve other muscles of the body.
It may be evident on imaging in the form of soft tissue calcification - the form of which may be variable.
It can occur as part of a paraneoplastic phenomenon in adults, such as in lung cancer.
