We investigated in this paper nineteen patients who had undergone removal of intrathoracic thyroid tumors. They were 4 males and 15 females, aged 22-73 years, on the pathological classification, 4 with follicular adenomas, 4 with adenomatous goiters, 6 with papillary carcinomas, 1 with follicular carcinoma, 3 with papillary and follicular mixed carcinomas and 1 with anaplastic carcinoma. A 10-year survival rate of carcinomas is 77.1%, and there were 4 cases that had long term interval (6-30 years) between removal of cervical thyroid carcinoma and finding out of intrathoracic thyroid carcinoma. One case of follicular adenomas gave rise to metastasis to lung after four years from removal of intrathoracic tumor, and so it is necessary to do a long term observation after removal of thyroid tumors.
