Abstract
The management of patients with incidentally discovered metastatic thyroid cancer in cervical lymph nodes in neck dissection specimens for other pathologies is unclear. Retrospective review of neck dissection specimens for nonthyroid malignancy during a 30-year period was undertaken to identify incidental metastatic papillary thyroid cancer (PTC). Twenty-six patients had an incidental finding of PTC in lymph node(s) in neck dissection specimens. Subsequent ultrasound of the thyroid showed nodules in 20 patients. Eleven (42%) underwent total thyroidectomy, 1 (4%) had a lobectomy, and 14 (54%) were kept under active surveillance only. At a median follow-up of 48 months (range 10-189 months), all patients who had undergone surgery and those under surveillance were free of PTC recurrence. Evaluation for detection of a primary thyroid tumor is essential in all patients with incidentally discovered metastatic PTC. Decision regarding surgery or surveillance is dependent on clinical and radiological tumor features and patient factors.
