title: [Corticosteroid responsive inflammatory myopathy with autoantibody against Golgi apparatus].
abstract: A 51-year-old woman of progressive myopathy predominantly involving proximal groups of limb-muscle was reported. Serum enzymes originating from the skeletal muscle always remained within normal range, and a positive autoantibody against Golgi apparatus and the SS-A (Ro) antibody in serum were noted. In muscle biopsy performed twice, extensive degenerating/regenerating fibers and sparce inflammatory cells between connective tissue elements in light microscopy, and disrupted lamellar structure of Golgi apparatus in electron microscopy were observed. Corticosteroid therapy was markedly effective. In the present case of a "so-called" limb-girdle syndrome, humoral autoantibodies, especially against Golgi apparatus, could induce a metabolic disturbance in the muscle fiber.
