Background:
Endoscopic thyroidectomy is widely accepted for its advantages. However, implant metastasis remains a significant complication of endoscopic thyroidectomy.
Methods:
This is the first report of breast implantation diagnosed with poorly differentiated thyroid carcinoma following endoscopic thyroidectomy.
Results:
We present a case of a 35-year-old woman who was initially diagnosed with a 3.0 cm conventional papillary thyroid carcinoma after endoscopic thyroidectomy via total areola. Two years later, she was reported to have recurring poorly differentiated thyroid carcinoma in the right areola. Implantation after endoscopic thyroidectomy is rare, and even rarer is dedifferentiated papillary thyroid carcinoma around the implant site.
Conclusions:
Stringently evaluated endoscopic surgery indications, appropriate preoperative evaluation, meticulous surgical technique, and adequate protective measures can significantly reduce the incidence of local implantation or recurrence.
