A case report of occult thyroglossal duct carcinoma
1Department of Otorhinolaryngology, Soka Municipal Hospital, Saitama, Japan.
Abstract:
A 50-year-old male had an occult thyroglossal duct carcinoma in the thyroglossal duct remnant attached to the upper pole of a thyroglossal duct cyst which was noticed due to extravasation of the cyst. After the patient had been struck into the thyroid cartilage with the tip of a bamboo sword while practicing Japanese fencing. The authors emphasize again that the important matter in the treatment of thyroglossal duct cysts is the removal of the whole thyroglossal duct remnant with the central portion of the hyoid bone according to Sistrunk's method in order to prevent not only recurrence of the thyroglossal duct cyst but also not to overlook any microcarcinoma.
