Dermatomyositis Presenting with Isolated Dysphagia: A Case Report / 대한신경근육질환학회지

ABSTRACT

We report a case of a 75-year-old woman who was diagnosed with dermatomyositis presenting with isolated dysphagia. There were no obvious cranial nerve deficits with normal motor grade in all the limbs in neurological examinations, but a suspicious rash was observed in the anterior chest. The serum creatine kinase was 306 IU/L, and active myopathic changes in bilateral limb muscles were observed in the electromyography test. Muscle biopsy from vastus lateralis showed perivascular infiltration of mononuclear inflammatory cells, which was compatible with dermatomyositis. She had responded to oral prednisolone and azathioprine.
