Abstract

Medullary thyroid cancer (MTC) represents less than 1% of all thyroid cancers. Complete surgical resection remains the mainstay of treatment for locoregional disease. Unfortunately, patients with recurrence may present with metastasis to challenging anatomic locations. We describe the first case of a recurrent MTC metastatic to the parapharyngeal space (PPS) that was managed using a combined transoral robotic surgery (TORS) and transcervical (TC) approach. We review the presentation, natural history, diagnosis and management of recurrent MTC, and describe a novel combined TORS–TC surgical approach for the treatment of PPS metastasis. A 66-year-old male with history of MTC treated with total thyroidectomy in 2000 and a liver resection in 2011 for metastatic MTC was referred to our Head and Neck Surgery Clinic in October 2016 due to increased calcitonin and CEA levels. Exam was significant for mild right tonsillar/pharyngeal bulging and induration. Imaging with PET–CT and MRI showed an enlarging ovoid mass centered within the right PPS without the presence of another systemic metastasis. FNA was consistent with MTC. The patient was taken to the operating room for a combined TORS–TC approach. Final pathology was consistent with metastatic MTC. Until recently, PPS tumors have been managed using highly morbid and cosmetically disfiguring open surgical approach. TORS provides a safe and effective alternative.
