Abstract

Hashimoto's thyroiditis has previously been associated with gonadal dysgenesis. Recent evidence suggests that Graves's disease and Hashimoto's thyroiditis are disorders of cell-mediated immunity and may have a common genetic predisposition. However, patients with both Graves's disease and the Turner syndrome have been reported only rarely. Three such cases are presented and the relation among gonadal dysgenesis, Hashimoto's thyroiditis, and Graves's disease is discussed.
