title: [Microscopic thyroid papillary cancers presenting as cervical lymph node metastases].
abstract: Microscopic papillary thyroid cancer (< 1 cm in diameter) is reputed to have an excellent prognosis. In 10 to 20% of cases, it presents in the form of lymph ode metastases. Immediately metastatic forms can be associated with unfavourable prognostic factors, such as multifocal tumours, extension to adjacent tissues, capsular effraction and development of distant metastases. We report 4 cases of microscopic papillary thyroid cancer presenting in the form of lymph node metastases. No primary thyroid lesion was palpable in any of these patients, but the subsequent course was complicated by ling metastases in one case. All patients underwent total thyroidectomy with lymph node dissection followed by adjuvant therapy with radioactive iodine and thyroxin inhibitory treatment. Lung metastases were observed in one case. The authors propose a therapeutic approach based on analysis of severity factors, which determine the recurrence rate.
