Papillary Carcinoma Arising from a Thyroglossal Cyst ―A Case Report―
A number of congenital lesions as well as malignant may arise in the neck. Thyroglossal cysts and sinuses are the most common anomalies encountered. They are derived from vestigues of the thyroglossal duct connecting the primitive median thyroid to its point of origin on the ventral wall of the pharynx. The presence of ectopic tissue in the thyroglossal cyst is occasionally observed. However, papillary carcinoma arising from a thyroid remnant is uncommon. In this paper, a case of papillary carcinoma developing from a thyroglossal cyst in a housewife of 47 was presented and its etiology was discussed.
