title: [Clinical and biological evolution of myasthenia gravis after thymectomy in a 13-year-old girl].
abstract: A 13-year-old girl suffering from rhumatoid arthritis developed a myasthenia gravis. Her circulating anti-acetylcholine receptor antibodies were observed before and after thymectomy. Surgical removal of the thymus was followed by complete clinical remission associated with a progressive decrease of the antibody level; these antibodies did not disappear completely even as late as 2 years after the operation.
