Thyroglossal duct cyst is thought to originate from the epithelial remnant of the thyroglossal duct. A cyst usually arises between the cecal foramen of the tongue and the thyroid gland. We report a rare case occurring in the tongue. A 61-year-old man was referred to the Department of Dentistry and Oral Surgery, Hospital because of swelling of the tongue. The mass of the tongue, 18×20mm, was elastic soft and purplish red. Magnetic resonance imaging indicated the presence of a cystic lesion. The lesion was enucleated for a clinical diagnosis of a cyst of the tongue. The pathological diagnosis was a thyroglossal duct cyst. There has been no evidence of recurrence as of 6 months after the operation, and the function of the tongue has improved.
