Papillary Carcinoma Within a Thyroglossal Duct Cyst

Thyroglossal duct cysts (TGDCs) are typically located in the midline of the neck. Carcinomas arising within these cysts are extremely rare, with papillary carcinoma being the most common type. Diagnosis is generally confirmed postoperatively following excision. We report the case of a 38-year-old female diagnosed with papillary carcinoma within a TGDC who underwent a Sistrunk procedure followed by a total thyroidectomy.
