Simultaneous occurrence of Graves' disease with endocrine ophthalmopathy. Thyroiditis and thyroid carcinoma.

The simultaneous occurrence of Graves' disease with ophthalmopathy lymphocytic and subacute de Quervains' thyroiditis has been observed in two male patients suffering from follicular-type thyroid carcinoma. In one of them Sjögren syndrome and a mild form of diabetes were also diagnosed. It is assumed, on the basis of indirect evidence, that the humoral and cellular lesions determined by genetic factors and influenced by prolonged thyrostatic and steroid treatment are jointly responsible for tumour genesis.
