A 42-year-old man developed a mass in the anterior neck which had increased in size in the past two months. A well circumscribed and firm mass was palpated at the midline of the neck below the hyoid bone. The clinical diagnosis was thyroglossal duct cyst. The mass was removed by Sistrunk's procedure. Histological examination showed a thyroglossal duct cyst with local involvement of malignant cells, suggesting papillary adenocarcinoma arising from the thyroglossal duct remnant. The patient's postoperative course was unremarkable for 19 months. Since thyroglossal duct carcinoma was rare, the clinical and pathological features were reviewed, and the method of diagnosis was discussed.
