The thyroglossal tract cyst is an uncommon developmental cyst which may form anywhere along the embryonic thyroglossal tract.
This article presents a case of thyroglossal cyst. The 31-year-old male patient complained of a tumor in the midline of the anterior neck for about one month. Ultrasonography showed an echo-free cystic pattern with a comparatively defined and irregular border. Computed tomography also revealed a cystic lesion with inflammation. An exploratory puncture aspirated yellow-colored mucoid fluid. Microorganisms were not isolated from fluid, and the cytology revealed basal cells, foam cells, macrophages, lymphocytes, keratin, and numerous neutrophils with no evidence of malignancy.
The cyst was excised under clinical diagnosis of thyroglossal cyst. A cord-like structure was seen to the level of the hyoid bone during the surgery, that followed Sistrunk's principles.
