A 21-year old Man with Distal Dominant Progressive Muscle Atrophy

症例呈示

　症例　T．T．21歳，男性。

　主訴　両下肢の筋力低下。

We report a 21-year-old man with distal domi-nant progressive muscle atrophy. The patient was apparently well until 17 years of age when he noted a decrease in exercise tolerance. One year later, he noted difficulty in raising his heels when he walked. He was admitted to our service for the work up in June 10, 1992.

On admission, the patient was rather slender in the body build up ; otherwise general physical exami-nation was unremarkable. Upon neurologic exami-nation, mental status and higher cerebral functions were normal.
