초록
The presence of lymph node metastasis of thyroid papillary carcinoma usually occurs in theinternal jugular and paratracheal space on the side of the lesion. For this reason, metastasis tothe retropharyngeal lymph nodes from papillary thyroid carcinoma is rare. We currently experiencedtwo cases of retropharyngeal lymph node metastasis of thyroid papillary carcinoma. Both patients had a history of total thyroidectomy and ipsilateral neck dissection and had undergoneretropharyngeal lymph node dissection via transoral approach after the diagnosis ofretropharyngeal node metastasis. We suggest that the metastatic retropharyngeal lymph nodescan be successfully removed through transoral apparoach. The diagnosis of this rare lymphnode metastasis requires sufficient imaging studies such as MRI, CT or PET-CT as well as appropriatehistory taking and physical examination.
