Papillary Thyroid Carcinoma with Extensive Cervical Lymph Node Metastasis and Initial Retropharyngeal Lymph Node Metastasis: A Case Report and Literature Review

Abstract

Papillary thyroid carcinoma (PTC) is prone to regional lymph node metastasis, which is more common in central lymph nodes and lateral cervical lymph nodes, and retropharyngeal lymph node metastasis (RLNM) is extremely rare. A male with PTC presented with extensive cervical lymph node metastasis and the initial RLNM. After full evaluation by preoperative imaging examination, the patient underwent total thyroidectomy + left central lymph node dissection + left neck lymph node dissection (II III IV V) + left retropharyngeal tumor resection, and the postoperative recovery was good without recurrence long-term complications, and no local recurrence and metastasis were found during one-year follow-up.
