It is classified as one of the idiopathic inflammatory myopathies (IIM). Although all idiopathic inflammatory myopathies share the common presentation of muscle weakness, they differ clinically in terms of muscle groups involved and histopathological findings.[1][2] Dermatomyositis. 6 The idiopathic inflammatory myopathies (IIM) are a group of autoimmune muscle diseases of which polymyositis (PM) and dermatomyositis (DM) are the most frequently recognized forms. Although the IIM are the most commonly acquired muscle diseases in adults, they are still rare in the general population with an estimated annual incidence of only. 7 There is a sixfold increased risk of malignancy in dermatomyositis (cf. twofold in polymyositis) 8.

Biochemically, several serum muscle enzymes are elevated, including CK. The degree of muscle pain and other symptoms varies widely. Most of the symptoms of rhabdomyolysis are nonspecific. 9 A diagnosis of dermatomyositis must also have at least four of the following criteria: Symmetrical muscle weakness in the shoulders/upper arms or hips/upper legs and trunk. Elevation of serum levels of skeletal muscle-associated enzymes: CK, aldolase, lactate dehydrogenase (LD or LDH), transaminases (ALT/SGPT and AST/SGOT) Short, small, low. paraneoplastische dermatomyositis 10 Alle angeführten Laborwerte können trotz Bestehens einer Dermatomyositis normal sein. · BSG ↑, CRP ↑. · Blutbild: Leukozytose, Lymphopenie, Eosinophilie. 11
