Abstract
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 was neither invasion to adjacent tissue nor lymph node involvement.The patient then underwent total thyroidectomy and bilateral neck dissection. The patient was treated with radioactive iodide and thyroid suppression therapy was given as adjuvant treatment.The patient has been following for two years without any metastasis.
Highlights
Thyroglossal duct cysts (TGDC) are the most common cause of neck mass in childhood, accounting for approximately 70% [1]
We presented two cases of female patients who presented to our hospital with asymptomatic neck masses developed gradually over years which were diagnosed with papillary carcinoma after Sistrunk’s procedure with total thyroidectomy
Case Reports:Case 1 A 45-year-old female patient had thyroglossal cyst for more than 10 years which was increasing in size recently with no dysphagia, shortness of breath, or hoarseness of voice
Summary
Thyroglossal duct cysts (TGDC) are the most common cause of neck mass in childhood, accounting for approximately 70% [1]. Thyroglossal duct cysts are most common etiology of midline neck We presented two cases of female patients who presented to our hospital with asymptomatic neck masses developed gradually over years which were diagnosed with papillary carcinoma after Sistrunk’s procedure with total thyroidectomy. Lack of such cases due to its rare entities especially in our region, necessitate more studies to establish clear guidelines for the management of thyroglossal duct cyst carcinoma.
