ABSTRACT
The inflammatory myopathies are divided into three major and distinct subsets: polymyositis (PM), dermatomyositis (DM) and inclusion body myositis (IBM). This distinction is based on rather unique clinical, laboratory, prognostic, therapeutic, demographic, histological and immunopathological criteria that have been previously addressed1-7. Among these disorders, IBM is the most common acquired inflammatory myopathy, especially in patients above the age of 50 years1-6. The condition presents with selective atrophy of forearm flexor muscles, frequent falls, atrophy of the quadricep muscles and dysphagia.
