[Pharyngeal dysphagia and polymyositis].

We report the case of a 70 year-old woman admitted for pharyngeal dysphagia. The diagnosis of polymyositis was made on manometry and histopathological neuromuscular biopsy findings. There were no inflammatory syndrome, muscular enzyme increase or electromyographic abnormalities. The patient was initially treated by prednisone (1 mg/kg/d) with success, but relapsed 12 weeks later and then was put on azathioprine (2 mg/kg/d). Pharyngeal dysphagia can be the only clinical manifestation of polymyositis, usually a systemic disease.
