Tract Site Seeding of Papillary Thyroid Cancer After Transoral Endoscopic Thyroidectomy: A Case Report

Abstract

The transoral endoscopic thyroidectomy vestibular approach (TOETVA) is an effective treatment for thyroid nodules and cancer. The excellent cosmetic outcomes compared to conventional and other types of endoscopic thyroidectomies make TOETVA a highly popular choice in selected patients. However, the limited working space and indirect thyroid manipulation can result in unexpected complications. Here, we describe a case of tract site seeding in a 47-year-old woman who underwent left hemithyroidectomy via TOETVA. The pathological diagnosis changed from follicular adenoma to invasive encapsulated follicular variant papillary thyroid cancer after cancer recurrence.
