Myositis mimics in scleroderma: A case series of neuromuscular diseases that can co-exist in scleroderma

Abstract

We present a case series of four patients with systemic sclerosis and skeletal myopathy. While idiopathic inflammatory myopathies, or myositis, are thought to be the most common type of muscle disease seen in systemic sclerosis, we highlight four cases where unique clinical findings and careful assessment ruled out myositis mimics. Key diagnostic tools that can be helpful for clinicians to diagnose a neuromuscular disease are also detailed in this report.
