Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

BACKGROUND We report a rare case of synchronous occurrence of thyroglossal duct cyst carcinoma and thyroid carcinoma and discuss its management in detail. METHODS A 59-year-old woman was clinically diagnosed to have a thyroglossal duct cyst and a solitary nodule. Fine-needle aspiration cytology revealed a papillary carcinoma in the thyroglossal duct cyst and a colloid in the thyroid nodule. S...

Thyroglossal duct cyst is the most commonly seen midline congenital neck masses found in children but are not uncommon in adults. The extension of the thyroglossal duct cyst into the larynx is very uncommon. Prelaryngeal thyroglossal duct cyst in a 60 year old man is described in this report. A laryngeal malignancy was suspected because of that cystic mass eroded the thyroid cartilage. The diag...

Thyroglossal duct cysts originate from persistent epithelial remnants of the thyroglossal duct that are present during the descent of the thyroid gland from the foramen cecum to its final position in the anterior neck. Thyroglossal duct may persist anywhere along the descent from the tongue to the thyroid. Lingually localized thyroglossal duct cysts are congenital lesions of the pharynx, which ...

Thyroglossal duct cysts are the most frequently encountered congenital neck masses having a malignancy rate of 1%. The most common malignant form is papillary thyroid carcinoma. Synchronous papillary thyroid carcinoma developing in the thyroglossal duct cyst is rarely seen. Synchronized papillary carcinoma can be described as a multifocal tumor or a metastatic lesion on a thyroglossal duct cyst...

Thyroglossal duct cysts are the most common form of congenital malformation in the neck. They develop from the epithelial remnants of the thyroglossal tract and 70% is diagnosed in childhood; 7% is diagnosed in adulthood. Carcinoma arising in these remnants constitutes a very uncommon histopathological entity. The diagnosis of malignancy is made incidentally on cytopathologic studies of the exc...

BACKGROUND AND PURPOSE Carcinoma arising in thyroglossal duct remnants is a well-described entity in the pathology and surgery literature, but it has little recognition in the radiology literature. Preoperative diagnosis may alter surgical management, although this diagnosis is rarely made. This study was undertaken to determine the radiologic features that might differentiate carcinoma from be...

BACKGROUND AND PURPOSE Thyroid carcinoma arising in a thyroglossal duct cyst may be clinically indistinguishable from a benign thyroglossal duct cyst. The preoperative diagnosis of carcinoma, however, can have important implications for surgical planning and postoperative treatment. Our purpose was to describe the CT appearance of thyroglossal duct carcinoma and identify the features that disti...

Although a thyroglossal duct cyst is a congenital anomaly, it can also appear in adults. Despite the presence of embryological remnants, it is still unclear why the cyst should suddenly develop later in life. We report a case of a 46-year-old male with an extravasation mucocele arising from a long-standing lingual thyroglossal duct remnant. MRI demonstrated a lingual cystic lesion near the hyoi...

Thyroglossal duct cyst is the most common developmental abnormality encountered in the neck. Carcinoma arising in a thyroglossal duct cyst is a rare occurrence, and was first reported by Ucherman in 1910, the most common being papillary carcinoma. The incidence of primary papillary carcinoma arising in thyroglossal duct cyst is less then1%. We report a case of papillary thyroid carcinoma occurr...
