OBJECTIVE. Myositis-specific autoantibodies (MSA) define relatively homogeneous clinical and immunogenetic patient groups in adults with idiopathic inflammatory myopathies (IIM). This study explores t...
We report a 72-year-old man with eosinophilic myositis (EM). At age 71 he noticed a painful nodule in his left calf. A biopsy (first biopsy) showed marked infiltration of mononucleated cells and necro...
Among the generalized chronic idiopathic inflammatory myopathies, inclusion body myositis (IBM) has emerged as a clinico-pathologic variant during the past two decades. It occurs primarily in elderly ...
Myositis specific autoantibodies (MSAs) are proven to be specific for myositis compared with other inflammatory connective tissue diseases. Their specificity compared, however, with other neuromuscula...
OBJECTIVE: To characterize serum autoantibody profiles of patients with idiopathic inflammatory myopathies (IIM) by searching for myositis-specific (MSA) and myositis-associated (MAA) antibodies with ...
