Thymic hyperplasia secondary to Graves’ disease (GD) is a well-recognized entity.¹ Still, other causes of thymic hyperplasia in the presence of euthyroidism, especially the occurrence of massive thymic hyperplasia, should be investigated.² The clinical features of myasthenia gravis (MG) and thyroid eye disease (TED) may be similar, while thymic hyperplasia may occur in both conditions. Herein, we report an interesting case of the coexistence of severe TED and MG.
