[8] Although dermatomyositis is closely related to polymyositis and is sometimes assumed to be a complication of that disease, most patients with dermatomyositis develop skin symptoms before any muscle involvement.
Autoimmune - Autoimmune disease is an abnormal immune response to specific body protein or other biomolecular target, such as one of the muscles. The three main types of idiopathic myositis (known as inflammatory myopathies) that typically test positive for autoantibodies are dermatomyositis, polymyositis, and inclusion body myositis. [4]

This action usually brings the disease under control, lowering most lab tests to or near normal values.

Image at right shows influx of inflammatory cells including eosinophils and neutrophils in the dermis (solid arrow) and blister cavity (dashed arrows), and deposition of fibrin (asterisks). [15] However, the diagnosis of bullous pemphigoid consist of at least 2 positive results out of 3 criteria: [19] Pruritus and/or predominant cutaneous blisters
Polymyositis and the associated inflammatory myopathies have an associated increased risk of cancer. [3] The features they found associated with an increased risk of cancer were older age, age greater than 45, male sex, difficulty swallowing, death of skin cells, cutaneous vasculitis, rapid onset of myositis (<4 weeks), elevated creatine kinase, higher erythrocyte sedimentation rate and higher ...
