Implantation at sternocleidomastoid and chest wall after endoscopic thyroid carcinoma surgery

Endoscopic thyroidectomy has been widely accepted by surgeons and patients for less postoperative pain, faster postoperative recovery, and excellent cosmetic effect. However, there still existed some limitations. Here, we reported a woman who suffered local implantation metastasis at sternocleidomastoid and chest wall after endoscopic thyroid carcinoma surgery. Although the implantation after endoscopic surgery is uncommon, this case reminds us to use endoscopic surgery for thyroid diseases with caution, especially for thyroid cancer. Following strict endoscopic surgery indications, comprehensive preoperative evaluation, meticulous intraoperative surgical handling, and effective protective measures, the incidence of locoregional implantation or recurrence might be dramatically reduced.
