Thyroglossal Duct Cyst Papillary Carcinoma: A Case Report and Review of the Literature

Abstract

Thyroglossal duct cyst is the most common congenital cyst, locating in the midline neck below the hyoid bone. Carcinoma occurring in a thyroglossal duct cyst is rare. Diagnosis generally depends on postoperative pathological diagnosis, because preoperative diagnosis is difficult, but imaging and fine-needle aspiration biopsy (FNAB) can help with the diagnosis. In addition, there is no consensus on the optimal management of thyroglossal duct cyst carcinoma. This paper describes a case of carcinoma in the thyroglossal duct cyst in a 60-year-old man and contains a review of the literature about the presentation, imaging manifestations and treatment.
