What is the Association between thymoma and Myasthenia Grevis ?
Approximately 15% of patients with Myasthenia Grevis have a thymoma, most of which are epithelial rather than lymphocytic in origin.
Ninety percent are benign and easily treated with resection, whereas 10% are malignant, carrying an average survival of 5 to 10 years.
Benign thymic hyperplasia is seen in about 50% of patients with Myasthenia Grevis.
