The thyroglossal duct cyst (TDC) is the most common anomaly observed during thyroid development, but carcinoma is found in approximately 1% of these lesions. To date, approximately 250 cases have been reported, the majority of them being papillary carcinoma (PC). The cysts are usually asymptomatic. The presentation of the patient with carcinoma is similar to TDC. The case we are reporting is a 36-years-old man who had been exposed to chemical warfare agents during the Iraq-Iran war. He presented with a cystic nodule above the thyroid, and the diagnosis of TDC was made during operation. Histopathology examination revealed PC in a TDC. Although thyroid examination and scan were normal, because of exposure to chemical warfare agents, total thyroidectomy was performed and revealed multifocal PC of the thyroid. Therefore, exposure to chemical warfare agents can be a high risk factor for thyroid malignancy, and total thyroidectomy in every case of PC to TDC with a history of chemical warfare injury is recommended.
