OBJECTIVES To report a rare case of thyroglossal duct cyst carcinoma which presented with obstructive sleep apnoea, and to highlight the difficulties in making this clinical diagnosis. METHOD Case report and review of the English language literature concerning thyroglossal duct cyst carcinoma. RESULTS Thyroglossal duct cyst carcinoma is a rare clinical entity found in only approximately 1 p...

The development of carcinoma in a thyroglossal cyst is rare. This report describes the presence of papillary carcinoma in a giant thyroglossal cyst and reviews the literature regarding the clinico-pathological features of the disease and its management.

Thyroglossal duct cysts are the most common congenital abnormalities of the neck, constituting about 70% of all cervical neck masses in children and 7% of the adult population. The occurrence of carcinoma in a thyroglossal duct cyst is very rare (less than 1%). Malignancy of the thyroglossal duct cyst usually presents in the third or fourth decade of life. We report a case of carcinoma in the t...

Thyroglossal cyst rarely presents with carcinoma formation in the remnants of the thyroid gland. We report a 40 year old male with papillary thyroid carcinoma formation in a thyroglossal cyst. The patient underwent surgical intervention for the cyst. His pathology was positive for thyroid carcinoma and he underwent complete thyroidectomy with postoperative radioactive iodine treatment. His foll...

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...

The thyroglossal duct cyst is a congenital lesion of the neck, resulting from the incomplete obliteration of the thyroglossal canal; in the embryonic period, its purpose is to facilitate the migration to the final seat of the thyroid draft. Rarely, the retention of this cyst can cause a neoplastic degeneration. A 33-year-old female presented to our outpatient clinic complaining of the appearanc...

Papillary carcinoma arising in thyroglossal cyst is rare and is usually detected on postoperative histopathology after routine Sistrunk operation. Further management is a matter of debate and the choice lies between regular follow-up after Sistrunk operation or total thyroidectomy with or without radioiodine ablation and thyroxine suppression therapy. Here, we present a case of papillary carcin...

INTRODUCTION Thyroglossal duct cysts account for approximately 70% of congenital neck abnormalities. Hoarseness of voice and the extension of the cyst into the larynx are very uncommon. CLINICAL PICTURE We present a patient with a long history of a large thyroglossal cyst who developed progressive hoarseness of voice. The cyst had protruded into the larynx producing the appearance of a laryng...

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...

INTRODUCTION The thyroglossal cyst is found in 7% of the population and the incidental papillary thyroid carcinoma in thyroglossal cyst is a rare entity with an incidence 1 to 2%. The clinical presentation is indistinguishable from a benign lesion and the histopathological postoperative study defines the diagnosis. Papillary carcinomas have favorable prognosis and cervical or distant metastases...
