1.1.Background: Necrotizing autoimmune myopathy is a relatively newly recognized rare form of idiopathic inflammatory myopathy. It presents clinically with symmetrical proximal muscle pain and weakness, associated with a markedly elevated Creatine kinase. These myopathies are usually immune mediated with a good response to immunotherapy.
1.2.Case presentation: We present a case of a 52 year old man of Asian descent, who presented with a 5 month history of symmetrical proximal muscle weakness. Patient underwent extensive workup and was diagnosed as having Necrotizing autoimmune myopathy with characteristic findings on muscle biopsy and positive HMGCR antibodies.
1.3.Conclusion:The disease process of Necrotizing autoimmune myopathy is still not completely understood. A delay in diagnosis may however lead to potential complications as the disease progresses rapidly.
