Autoimmune hepatitis and dermatomyositis: a rare association

The association between autoimmune hepatitis and idiopathic inflammatory myopathies has been rarely described in literature. To our knowledge, there are only five reports of autoimmune hepatitis, all coursing with polymyositis. In the present work, we describe a female patient at the age of 58 with cutaneous lesions (heliotrope), progressive proximal muscle weakness of four limbs and constitutional symptoms for 12 months, and worsened two months ago. She had also been episodes of jaundice for five months. During hospitalization, after intense clinical investigation, the diagnosis of dermatomyositis and autoimmune hepatitis were defined, and the patient had a good clinical and laboratory response to corticosteroids and immunosuppressive.
