[Multiple papillary carcinoma of thyroid with extensive metastasis of the lateral neck and parapharyngeal: a case report].

Thyroid papillary carcinoma(PTC) is the most common type of thyroid cancer. The 2017 NCCN guidelines reported that PTC accounts for 89.4% of thyroid cancer, and papillary thyroid cancer is well known to most head and neck surgeons due to its weak invasiveness, good surgical excision rate and low recurrence rate. However, as the treatment progresses, we may also touch the rapidly progressing PTC, or even the paropharyngeal metastasis in a short period of time, and the reported rate is 0.43% to 2.5%.
