Subcutaneous implantation of thyroid carcinoma and benign tissue after thyroidectomy: report on two cases and review of the current literature.

Subcutaneous implantation of benign thyroid tissue or thyroid cancer can occur after thyroidectomy. Minimizing the likelihood of subcutaneous implantation requires careful consideration of various factors at every stage of the surgical procedure. Surgeons should be aware of this potential long-term complication that can occur in both conventional thyroidectomy and remote access surgery, effectively communicate and provide appropriate guidance to their patients, and try to avoid seeding of both malignant and benign thyroid tissue.
