[Occult carcinoma of the thyroid].
We reviewed the clinical and pathologic data of the 135 cases with occult carcinoma of the thyroid (OCT) between 1962 and 1991. 54 cases were found incidental to thyroid operation (group I), 77 cases were found primarily by cervical node metastasis (group II), 3 were found at the time of operation for other tumors of the head and neck and 1 was traced by distant metastasis. All patients were treated surgically in our service. Mean follow-up period was 10 years. None of patients died from causes related to OCT in group I. 6 cases died of the cancer in group II, hence a 10-year survival of 81.25%. Based on our clinical observations, OCT could be divided into two types. Type I is that found incidentally by thyroidectomy which usually with good prognosis. Type II which was evidenced by nodal metastasis tends to follow a poor postoperative course.
