Reference work entry


The overlap syndromes are characterised by a combination of major features of one or more rheumatic diseases, and mixed connective tissue disease (MCTD) is a special form of overlap syndrome. Inflammatory myopathies are idiopathic and acquired and are differentiated into several subsets, namely, dermatomyositis, the most common; polymyositis, least common; inclusion body myositis, most common above the age of 50; overlap myositis; cancer-associated myositis; and immune-mediated necrotizing myopathy.
