ABSTRACT
Objective@#To report a case of thyroglossal duct carcinoma with concurrent papillary thyroid carcinoma @*Methods@#Design: Case Report. Setting: Tertiary National University Hospital. Patient: One. @*Results@#A 46-year-old woman was diagnosed with thyroglossal duct carcinoma after undergoing a Sistrunk procedure. Due to presence of thyroid nodules, the patient underwent second stage thyroidectomy with central neck dissection which revealed papillary thyroid carcinoma. @*Conclusion@#Thyroglossal duct carcinomas are rare entities and there is no current consensus regarding their management. Difficulties arise in the diagnosis of these tumors as they present similarly to benign thyroglossal duct cysts. Most cases are diagnosed postoperatively. Proper preoperative assessment including head and neck examination, biopsy, and radiologic imaging is necessary to recognize patients who could benefit from more aggressive management.
