A Novel Presentation of Refractory Immune Thrombocytopenia in Anti-synthetase Syndrome: A Case Report.

Anti-synthetase syndrome (AS) is a rare autoimmune disorder classified among the idiopathic inflammatory myopathies and is characterized by antibodies directed against aminoacyl-transfer RNA synthetases and the presence of myositis, interstitial lung disease, ±arthritis. Here, we report, for the first time, immune thrombocytopenia (ITP) in a patient with AS. This case reports a new association of AS with ITP and highlights the utility of identifying the underlying driver in secondary ITP to guide therapy.
