Thyroglossal duct cyst is a congenital anomaly resulting from retention of a thyroglossal duct during embryonic development.<BR>Thyroglossal duct cysts usually arise at in the midline of the neck and are rarely found in the oral cavity. We describe an infant who was born with a thyroglossal duct cyst in the oral floor, which interferred with nursing.<BR>The patient was a 4-day-old male infant. An elastic soft mass was palpable in the floor of the mouth. The mass was clinically diagnosed as a thyroglossal duct cyst because of its cystic structure on computed tomographic examination.<BR>For treatment, the cyst was successfully enucleated via a transoral approach. We did not resect the hyoid bone.<BR>Histopathologically, the cyst was covered with columnar and stratfied squamous epithelium. Thyroid tissue was not found.<BR>There has been no evidence of recurrence as of 6 years after the operation.
