title: Long-term follow up of thymus in patients with myasthenia gravis.
abstract: We examined transversely the thymus of 33 myasthenia gravis (MG) patients followed up for more than 5 years and found three thymomas. One was found 21 years after thymoma resection (Masaoka I, WHO Type B2 thymoma) and extended thymectomy. The other two were non-thymomatous at onset, and they were not treated with extended thymectomy. Therapeutic guidelines should mention the importance of follow-up in MG thymus.
