ABSTRACT

Malignant lesion of a thyroglossal duct cyst (TGDC) is an extremely rare entity. Papillary carcinoma is the most common malignancy of the endocrine system. Diagnosis is commonly made after pathological examination of the surgical specimen. A 41-year-old male patient with a midline neck mass was initially diagnosed with a thyroglossal duct cyst and underwent a Sistrunks procedure. Histopathologic examination revealed a papillary thyroid car¬cinoma within the thyroglossal duct cyst. Ultrasound elastography of the thyroid gland was performed. We have detected a hypoechoic hypervascular thyroid nodule measuring 3 mm in diameter that appeared completely blue in B-mode ultrasonography, and hard tissue was visualized by elastosonography (ES). The patient then underwent total thyroidectomy and bilateral neck dissection. The final pathological finding showed papillary microcarcinoma of the thyroid gland without cervical lymph node metastasis. When a thyroglossal duct cyst is excised using Sistrunk’s procedure and when the definitive hystological analysis depicts malignancy, the thyroid gland must be studied carefully with radiological examinations.
