Obstructive sleep apnea (OSA) is a common disorder. It usually results from the structural compromise of the upper airway. In patients with OSA, the obstruction predominantly occurs along the pharyngeal airway, and also a variety of tumors have been reported to cause such a condition. We present here the case of a thyroglossal duct cyst causing OSA in adult. This case demonstrates that thyroglo...

thyroglossal duct cysts are the most common form of congenital cysts on the neck. the incidence of thyroid papillary carcinoma in thyroglossal duct cyst is less than 1%. in most cases the diagnosis is made postoperatively. we present a 22-year-old female with thyroid papillary carcinoma arising from thyroglossal duct cyst,identified in pathologic study after sistrunk operation.in our case there...

BACKGROUND AND PURPOSE Thyroglossal duct cyst remnants (TGDC) are a common midline neck mass that is mostly encountered in childhood. Enlargement after an upper respiratory tract infection or, rarely, cancer within TGDC, is a well-documented phenomenon. In the pediatric population, it rarely presents a diagnostic quandary. However, in an adult population, especially one treated for head and nec...

type of midline neck masses in children. Though usually benign, 1% of cysts may undergo neoplastic change. The most common histological subtype is papillary carcinoma (80%) followed in order of frequency by mixed follicular-papillary, squamous, follicular, anaplastic, and hurthle-cell carcinoma (1). The synchronous occurrence of thyroglossal duct carcinoma and thyroid carcinoma in the thyroid g...

Laryngeal cysts involving the valleculae are rare but well known cause of upper respiratory obstruction. Vallecular cysts are uncommon lesions seen in the pediatric population and mostly present within the first few weeks of life. They may present with diversity of clinical signs and symptoms including failure to thrive, stridor and respiratory distress. Thyroglossal duct cyst, on the other han...

Abstract Introduction Thyroglossal cyst is one of the most common benign congenital neck lumps, however, incidental malignancy in these cysts a rare entity with incidence rate <1%. Method We present case 35-year-old female, who presented an asymptomatic midline mass. ultrasound confirmed 3.5 cm thyroglossal duct (TDC). She underwent Sistrunk procedure to excise cyst. On histological exam...
