PRIMARY THYROGLOSSAL DUCT CYST PAPILLARY CARCINOMA: A CASE REPORT

A Thyroglossal duct cyst (TGDC) is the most frequent congenital cervical anomaly (~70% in children and 7% in adults) in the development of the thyroid gland. However, incidence of carcinoma arising from a TGDC is extremely rare (≤1%) and is diagnosed during the pathologic examination of thyroidectomy specimen. To date, only fewer related cases have been reported to the literature. Among those cases, only few were diagnosed as primary TGDC papillary carcinoma. Here in, we present a case of 25- year old woman with primary TGDC papillary carcinoma identified after sistrunk surgery. Later on, patient underwent total thyroidectomy, bilateral neck dissection and adjuvant radioactive iodine ablation. The patient was alive and without any recurrence at fifth year of follow-up after her initial diagnosis.
