CONCURRENT HYPERTHYROIDISM AND THYROID-CARCINOMA

Between 1986 and 1991, thyroidectomy was performed on 138 patients wit h hyperthyroidism. Thyroid carcinoma was found in eight patients (5.8 per cent). Eighty (58-0 per cent) of the 138 patients had toxic nodula r goitre, 33 (23.9 per cent) toxic diffuse goitre and 25 (18.1 per cen t) toxic adenoma. Concurrent carcinoma was more frequent in patients w ith toxic adenoma (8 per cent) than in those with Graves' disease (6 p er cent) and toxic nodular goitre (5 per cent). Papillary carcinoma wa s found in seven patients and follicular carcinoma in one. Three papil lary carcinomas were occult with a diameter less than 1.5 cm. Five pat ients received 100 mCi I-131 after operation. There was no morbidity. During follow-up of 10-45 months, there was neither death nor recurren ce.
