Thymic hyperplasia is frequent in patients with Graves’ disease (GD) but it rarely is large enough to be detected radiologically as an anterior mediastinal mass. In the few cases operated, lymphoid hyperplasia (i.e. lymphoid follicle proliferation with expansion of both the cortical and the medullary component) has been documented histologically in 38% of cases, while true thymic hyperplasia, i.e. thymic enlargement with normal tissue architecture, was found...
