Dermatomyositis (DM) is an autoimmune inflammatory myopathy characterized by features of a typical rash, proximal muscle weakness, and evidence of muscle inflammation. Acute inflammatory demyelinating polyneuropathy (AIDP) is an autoimmune peripheral nerve disease characterized by myelin damage and progressive areflexic weakness and sensory changes. AIDP can be precipitated by viral infections such as Epstein-Barr virus (EBV). We present a case of DM with rhabdomyolysis and necrotizing features, along with AIDP in the setting of EBV viremia. DM and AIDP rarely coincide together. The patient was treated with a combination therapy of methylprednisolone, azathioprine, and intravenous immunoglobulins (IVIGs), which led to significant improvement in his symptoms.
