The Disappearance of a Hepatic Mass in Anti-Synthetase Syndrome

Abstract

Anti-Synthetase Syndrome (ASyS) is a rare chronic autoimmune disorder characterized by myositis, interstitial lung disease (ILD), polyarthralgia, “mechanic’s hands” and Raynaud’s phenomenon. Liver lesions are quite rare in ASyS. In our ASyS case, we will discuss a 58-year-old man presenting with muscle weakness, arthralgia, and interstitial lung disease (ILD). He was positive for anti-Jo-1 antibodies, substantiating the diagnosis, and was started on treatment. This was followed by the appearance of a liver mass that disappeared when the patient achieved remission.
